Moraxella catarrhalis is a human-restricted commensal that over the last two decades has developed into an emerging respiratory tract pathogen. The bacterial species is equipped with various adhesins to facilitate its colonization. Successful evasion of the human immune system is a prerequisite for Moraxella infection. This strategy involves induction of an excessive proinflammatory response, inte
Recent Hubble Space Telescope observations of a large sample of globular clusters reveal that every cluster contains between 40 and 400 blue stragglers.The population does not correlate with either stellar collision rate (as would be expected if all blue stragglers were formed via collisions) or total mass (as would be expected if all blue stragglers were formed via the unhindered evolution of a s
Aim: Does metabolic control improve in children with insulin dependent diabetes mellitus (IDDM), when modifying the quality of carbohydrates by introducing low glycaemic index (GI) foods? Methods: The inclusion criteria for the study was children with diabetes mellitus type 1, age from 7 to 11 years old, they should have a moderate glucose control with HbA1c between 7,5 to 8,5 and no allergy to ce
All living cells require specific mechanisms that target proteins to the cell surface. In eukaryotes, the first part of this process involves recognition in the endoplasmic reticulum of amino-terminal signal sequences and translocation through Sec translocons, whereas subsequent targeting to different surface locations is promoted by internal sorting signals(1). In bacteria, N-terminal signal sequ
We study close encounters involving massive main-sequence stars and the evolution of the exotic products of these encounters as common-envelope systems or possible hypernova progenitors. We show that parabolic encounters between low- and high-mass stars and between two high-mass stars with small periastrons result in mergers on time-scales of a few tens of stellar free-fall times (a few tens of ho
We study the effects of NaCl on the self-assembly of AAKLVFF and beta A beta AKLVFF in solution. Both AAKLVFF and beta A beta AKLVFF self-assemble into twisted fibers in aqueous solution. The addition of NaCl to aqueous solutions of AAKLVFF produces large crystal-like nanotapes which eventually precipitate. In contrast, highly twisted fibrils were observed for beta A beta AKLVFF solutions at low s
This study examined variability of lip movements across repetitions of the same utterance as a function of age in Swedish speakers. The specific purpose was to extend earlier findings by examining variability in both phase and amplitude. Subjects were 50 typically developed native Swedish children and adults (28 females, 22 males, aged 5-31 years). Lip movements were recorded during 15-20 repetiti
Prophylactic vaccines against human papillomavirus (HPV) based on Virus-Like Particles (VLPs) induce type-specific neutralizing antibodies against a small number of hypervariable residues positioned in surface-exposed loops of the major capsid protein L1. To investigate the importance of these residues for neutralization, cross-neutralization, L2 incorporation and genome encapsidation, ten surface
Rheumatoid arthritis (RA) is a chronic inflammatory disease directed towards peripheral joints. As all common diseases it is associated with several genes and a multitude of environmental factors. In addition, in similarity with most other complex diseases, it is defined only on the basis of clinical signs and symptoms, it is therefore more properly classified as a syndrome rather than a distinct
The focus of the presentation is on the individual’s comprehension of “citizenship”. Study and analysis of citizenship concerns a person’s co-operative interaction with various physical and social surroundings as well as the cognitive integration of these surroundings. A person can achieve this integration through development of his abilities of judgement. Thus the aim is to make apparent the kind
A new sampler with embedded FIR filter was designed with the charge sampling technique. The filter functions by summing the weighted current on a passive capacitor and the weighting factors are decided by the FIR coefficients. The performance of the filter can well compete with conventional analog filter but with smaller area and less power consumption. A testing chip was designed with 2 V supply,
Syftet med denna studie är att analysera hur personal inom socialtjänsten tolkar, definierar och upplever ett behandlingsprojekt, som involverade olika myndigheter, benämnt Motverka Våld och Gäng. Dessutom uppmärksammas hur den intervjuade och observerade personalen uppfattar och kategoriserar de inom projektet anställda samordnarna. De anställda inom socialtjänsten upplever att projektet kommitThe aim of this study is to analyze how the Social Services personnel interpret, define and perceive, on the one hand, the project “Motverka Våld och Gäng” meaning “Counteract Violence and Gangs”, and on the other hand the role of the Coordinators employed in this project. Heads of units and Social Secretarys were interviewed, as well as observed and recorded at meetings. The personnel of the Soc
