Tendon autografts for bridging nerve defects

Popular Abstract in Swedish Bakgrund En skada i en extremitet, som innebär att en perifer nervstam blir avskuren, medför ofta ett betydande handikapp med förlust av muskelkraft och känsel för patienten och därtill stora samhällskostnader, eftersom sådana skador i stor omfattning drabbar den arbetsföra delen av befolkningen. Det bästa behandlingsalternativet vid en sådan skada är att direkt sy ihoA new method, where a tendon segment – a tendon autograft – was used as graft material for peripheral nerve reconstruction, was developed. Defects, 10-15 mm long, in rat sciatic nerves were bridged by various modifications of tendons. A piece of an intact tendon and a tendon, that had been teased into a membrane and then rolled to form a loose “collagen roll”, supported axonal regeneration over a

Öppningar: möten med bibeln

Författarna till denna bok, som är en bok om många böcker, vill erbjuda öppningar till bibeln där text och läsare kan mötas. Boken handlar om att känna igen bibeln, om att berätta bibelns historia, om att leva med bibeln, om att tro på Gud med bibelns hjälp och om att söka kärleken med bibeln. Men den handlar också om att uthärda bibeln och om att kritisera bibeln. För till bibelns verkningshistor

Doing archaeology in popular culture

The popular image of archaeology and what archaeologists do is based on various clichés which emphasise, among other things, adventurous fieldwork, the discovery of treasures and historical detective work. Although archaeologists may see themselves differently, their image in popular culture reveals a lot about how the subject is perceived and why it is so widely appreciated at present. I suggest

Multi-jumps

We provide clear-cut evidence for economically and statistically significant multivariate jumps (multi-jumps) occurring simultaneously in stock prices by using a novel nonparametric test based on smoothed estimators of integrated variances. Detecting multi-jumps in a panel of liquid stocks is more statistically powerful and economically informative than the detection of univariate jumps in the mar

Ånej, medborgare! Per Albin Hansson och politikens medialisering

The essay studies the ways in which the Swedish Prime Minister, Per Albin Hansson, was mediated in the 1930s and 40s. In contrast to an existing belief that the medalization of politics didn't really evolve until the breakthough of television during the 1960s and 70s, it is suggested that this way of relating to politics existed at a significantly earlie stage of Swedish media history.

Light-Matter Interaction on the Attosecond Timescale

Popular Abstract in Swedish När ljus belyser ett material kan elektroner frigöras via en process som kallas den fotoelektriska effekten. Experiment utförda under slutet av 1800-talet visade att det inte är styrkan på ljuset som avgör om elektroner kan frigöras, det är istället ljusets färg. Rött ljus har en låg frekvens och blått ljus har en hög frekvens, men hur kan denna frekvens spela en så avgAttosecond science refers to physical processes that occur on the natural timescale of electron motion in atomic and molecular systems. Attosecond time resolution can be obtained experimentally through a process called high-order harmonic generation where sharp attosecond pulses are formed in the time domain. Attosecond pulse trains contain many attosecond pulses with a constant pulse-to-pulse s

A general model of resonance capture in planetary systems: first- and second-order resonances

Mean motion resonances are a common feature of both our own Solar system and of extrasolar planetary systems. Bodies can be trapped in resonance when their orbital semimajor axes change, for instance when they migrate through a protoplanetary disc. We use a Hamiltonian model to thoroughly investigate the capture behaviour for first- and second-order resonances. Using this method, all resonances of

The role of leucine-rich repeat glycoproteins/proteoglycans in the assembly of collagen matrices

Popular Abstract in Swedish Bindväv är samlingsnamnet på de vävnader som bygger upp ben, brosk, senor, ligament, tänder, hud m.m. Bindväven utgör kroppens stomme och bidrar med stödjande och elastiska funktioner samt ger skydd åt kroppen både på utsidan och åt de inre organen. Det finns ganska få celler i bindväv jämfört med många andra vävnader i kroppen och det finns olika celltyper i olika sortThe properties of different connective tissues depend on the synthesis and assembly of macromolecular structures composed of collagen and other extracellular matrix components. Mechanisms modulating these events play important roles in the formation of a functional tissue. We have studied the role of collagen-binding extracellular matrix leucine-rich repeat glycoproteins/proteoglycans in the forma
