    The effect of polystyrene sodium sulfonate grafting on polyethylene terephthalate artificial ligaments on in vitro mineralisation and in vivo bone tissue integration

    This study investigates the impact of polystyrene sodium sulfonate (PolyNaSS) grafting onto the osseointegration of a polyethylene terephthalate artificial ligament (Ligament Advanced Reinforcement System, LARS ) used for Anterior Cruciate Ligament (ACL). The performance of grafted and non-grafted ligaments was assessed in vitro by culturing human osteoblasts under osteogenic induction and this demonstrated that the surface modification was capable of up-regulating the secretion of ALP and induced higher level of mineralisation as measured 6 weeks post-seeding by Micro-Computed Tomography. Grafted and non-grafted LARS were subsequently implanted in an ovine model for ACL reconstruction and the ligament-to-bone interface was evaluated by histology and biomechanical testings 3 and 12 months post-implantation. The grafted ligaments exhibited more frequent direct ligament-tobone contact and bone formation in the core of the ligament at the later time point than the nongrafted specimens, the grafting also significantly reduced thefibrous encapsulation of the ligament 12 months post-implantation. However, this improved osseo-integration was not translated into a significant increase in the biomechanical pull-out loads. These results provide evidences that PolyNaSS grafting improved the osseo-integration of the artificial ligament within the bone tunnels. This might positively influence the outcome of the surgical reconstructions, as higher ligament stability is believed to limit micro-movement and therefore permits earlier and enhanced healing.Programme ANR LIGAR

    [Neurotrophic factors in the CNS. Increasing numbers of proteins with clinical potential]

    No full text
    The great Anders Jahre Prize, for 1995, for medical research, is to be shared by Professor Lars Olson, Stockholm, and Professor Anders Björklund, Lund. Lars Olson is one of the pioneers responsible for mapping the neural pathways of the brain. He has also systematically studied the mechanisms underlaying nerve cell growth and clucidated the growth factors involved. Our knowledge of the proteins necessary to neuron survival, nerve fibre growth, and the maintenance of synapses is increasing very rapidly. In a long-term perspective, this will open up new approaches to the treatment of a number of neuropathological diseases, eg, Parkinson's disease, and to the repair of nerve tissue, eg, after stroke

    Author Functions in Lars Kepler\u27s The Hypnotist: An Analysis

    No full text
    This paper examines Foucault\u27s notion of the author function as it pertains to Lars Kepler\u27s bestselling 2011 crime thriller, The Hypnotist. Lars Kepler is the pseudonym of a Swedish husband-wife writing duo, making him the perfect subject for analysis centering on illusory notion of the author. This paper will answer these questions: Who is the true author of The Hypnotist? What factors influence the author function of this bestelling novel? And what can The Hypnotist phenomenon tell us about the relationships between authors and their readers? This paper will demonstrate that no literary works may be ascribed to an individual person, and that authors hold no privileged knowledge of the works they produce, because authors cease to be authors the moment pen is lifted from page

    ”Lärda nyheter” i Peter Hernquists korrespondens till Carl von Linné och Abraham Bäck - med kommentarer och utvikningar

    No full text
    I detta Meddelande nr 55 från Veterinärhistoriska museet har författaren - professor emeritus Lars-Erik Appelgren - gjort ett urval av den korrespondens som Peter Hernquist hade med sina mentorer Carl von Linné och Abraham Bäck under sin vistelse i Frankrike, varvid ”Lärda nyheter” varit en ledstjärna för urvalet. Speciellt har breven till Bäck försetts med författarens personliga kommentarer men även kompletterats med faktaupplysningar från andra källor än breven om berörda nyheter. För att underlätta läsningen har dessa kommentarer omgetts med enkelkonturerad och utvikningarna med dubbelkonturerad ram. Lars-Erik Appelgren har inte bara genom sitt veterinärhistoriska författarskap utan också genom att ställa sina fackliga kunskaper och sin eminenta estetiska läggning till förfogande gjort Veterinärhistoriska museet ovärderliga tjänster. Det är med stor glädje jag noterar att region Uppsala nyligen visat sin uppskattning genom att tilldela Lars-Erik sitt Medicinhistoriska stipendium med motiveringen att de vill ”lyfta fram ett viktigt men ofta förbisett område inom medicinhistorien: veterinärmedicinen”. Med de varmaste gratulationer

    Interpreting Wage Bargaining Norms

    No full text
    From the mid-1990s onwards, Swedish wage bargaining has been characterised by informal co-ordination of the wage claims of big unions and bargaining cartels. In particular, it has been understood that the manufacturing sector should lead by first agreeing on a pay increase, whereafter the service sector and public sector unions choose a similar increase. We analyse his setup with two possible theoretical interpretations: (i) the manufacturing sector as a tackelberg leader and (ii) a normative role for the manufacturing sector’s pay increase, upported either by unmodelled social pressure or a modeled loss aversion (envy) of the heltered sector unions. The conclusion of the analysis is that the normative or leading role of one sector – in the Swedish case the manufacturing sector – can potentially bring big benefits for employment and output. Generalising an idea suggested by Lars Calmfors and Anna Larsson, our analysis also generates a rudimentary theory of why the wage increase norm sometimes binds and sometimes not. A comparison of the model predictions and the observed outcomes of the last five wage bargaining rounds in Sweden suggests that the model is generally consistent with the empirical observations: wage moderation and norm observance are stronger when the manufacturing industry’s initial relative wage is low.wage bargaining; bargaining co-ordination

    Representation of female characters in the films of Lars von Trier

    Oslanjajući se na sličnosti u ženskim likovima Lars Von Triera, detektirani su patrijarhalni i religijski obrasci koji su okosnica radnje filmova Lomeći valove, Dogville i Antikrist. Kroz religijsku i patrijarhalnu optiku autor čita Lars Von Triera kao redatelja koji istu optiku kritizira i preispituje u svom stvaralaštvu.Relying on the similarities in Lars von Trier's female characters, patriarchal and religious patterns have been detected that are the backbone of the plot of the films Breaking the Waves, Dogville and the Antichrist. Through religious and patriarchal optics, the author reads Lars Von Trier as a director who criticizes and questions the same optics in his work
