Aim: This study investigated the relationship between sexual debut before 14 years of age and socio-demographics, sexual experience, health, experience of child abuse and behaviour at 18 years of age. Methods: A sample of 3432 Swedish high school seniors completed a survey about sexuality, health and abuse at the age of 18. Results: Early debut was positively correlated with risky behaviours, such
It is important to understand the role that different predators can have to be able to predict how changes in the predator assemblage may affect the prey community and ecosystem attributes. We tested the effects of different stream predators on macroinvertebrates and ecosystem attributes, in terms of benthic algal biomass and accumulation of detritus, in artificial stream channels. Predator richne
The beta decay of five heavy, neutron-rich nuclei, Pt-203,Pt-204 and Ir200-202, has been investigated following relativistic cold fragmentation reactions of lead projectiles using the FRS + RISING setup at GSI. This paper reports on the study of the low-lying states in the decay daughter nuclei Au-203,Au-204 and Pt200-202. The characteristic gamma rays for each nucleus have been determined using b
In Order to differentiate the semiotic capadties of animals and human beings we need to understand more exactly wfaat these properties are. Instead of identifymg all vehicles of meaning with signs, we certainly have to spedfy the notion of sign, but it will also be necessaty to provide an inventory of other kinds of meaning, staiting out from perception, and going through a number of intermediate
Background: In order to get global molecular understanding of one of the most important crop diseases worldwide, we investigated compatible and incompatible interactions between Phytophthora infestans and potato (Solanum tuberosum). We used the two most field-resistant potato clones under Swedish growing conditions, which have the greatest known local diversity of P. infestans populations, and a r
The location of embryonic lymph node development is determined by the initial clustering of lymphoid tissue-inducer (LTi) cells. Here we demonstrate that both the chemokine CXCL13 and the chemokine CCL21 attracted LTi cells at embryonic days 12.5-14.5 and that initial clustering depended exclusively on CXCL13. Retinoic acid (RA) induced early CXCL13 expression in stromal organizer cells independen
Background and aim of the study: The logistic EuroSCORE and STS score have been used for the selection of suitable TAVI patients, but their predictive ability is unsatisfactory. The study aim was to evaluate the performance of the EuroSCORE II in predicting 30-day mortality after TAVI in comparison to the logistic EuroSCORE and STS scoring systems. Methods: Between January 2008 and April 2013, a t
Results from interviews with representatives from 13 Swedish municipalities and studies of fire protection documentation are presented in this report. The results provide an overview of the typical fire protection systems used to prevent deliberately lit fires in schools and kindergartens. There is great variety of which fire protection systems that is used in the municipalities. The measures ment
Abstract in UndeterminedDue to his background as a Platonist, Justin Martyr’s relation to Stoic philosophy has not gained as much attention from scholars as his relation to Platonism, and his relationship to contemporary Stoicism has been largely overlooked. The present essay provides an overview and analysis of Justin’s references and allusions to Stoics and Stoic philosophy, with particular focu
Here the feasibility of layers based on the conducting polymer polyaniline (PANI) as component of glucose biosensors using glucose oxidase (GOx) as enzyme and [Os(bpy)(2)(4-aminomethylpyridine)Cl]PF6 (OsCmplx) as electrochemical mediator, is evaluated. Particularly, PANI was employed to obtain a nanostructured macroporous material (m-PANI) around polystyrene nanoparticles taken as template and the
Post-sternotomy mediastinitis is a serious complication after cardiothoracic surgery and contribute significantly to post-operative morbidity, mortality, and healthcare costs. Negative pressure wound therapy is today's golden standard for post-sternotomy mediastinitis treatment. A systematic literature search was conducted at PubMed until October 2012 to analyse whether vacuum-assisted closure tec
In a recent study,Westerlund (Empir Econ 37:517–531, 2009) shows that the performance of the popular LLC (Levin et al., J Econ 108:1–24, 2002) panel unit root test depends critically on the choice of lag truncation used when correcting for serial correlation, and that it is only when this parameter is set as a function of time that the power raises above size. The purpose of the current paper is t
To probe internal motions in proteins on the 10−8−10−5 s time scale by NMR relaxation, it is necessary to eliminate protein tumbling. Here, we examine to what extent magnetic relaxation dispersion (MRD) experiments on the water 1H resonance report on protein motions in this time window. We also perform a critical test of two physically distinct mechanisms that have been proposed to explain and int
Hematopoietic stem cells (HSC) are multipotent and possess self-renewal capacity. Thus, they can sustain a life-long hematopoiesis and are also capable of restoring the hematopoietic system when transplanted to a patient. In allogeneic hematopoietic stem cell transplantation (HSCT), a potent graft-versus-leukemia (GvL) effect must be balanced against the concomitant risk of severe immunological re
Popular Abstract in Swedish Drygt en tiondel av Sveriges befolkning lider av hjärt-kärlsjukdom som också är den vanligaste dödsorsaken. Många av de akuta sjukdomstillstånden orsakas av att en bit inflammerad blodkärlsvävnad bryts loss från sitt fäste i något av de stora blodkärlen, färdas med blodet och täpper till blodflödet i mindre blodkärl. Detta leder till syrebrist och celldöd nedströms om dAbstract Atherosclerosis is a multifactorial disease, but an unbalanced immune system plays a critical role in the disease development. A common theory states that a continuous stress to the vascular vessel wall initiates a repair process that however is insufficient to completely heal the tissue. This imbalance is associated with accumulation of cholesterol, which is an essential component of ce
Background and purpose Adequate depth of cement penetration and cement mantle thickness is important for the durability of cemented cups. A flanged cup, as opposed to unflanged, has been suggested to give a more uniform cement mantle and superior cement pressurization, thus improving the depth of cement penetration. This hypothesis was tested experimentally. Materials and methods The same cup desi
