Objective. Time to theoretical indication of joint replacement surgery has been proposed as a primary outcome for potential structure-modifying interventions for osteoarthritis (OA). The objectives of this OMERACT/OARSI Working Group were to identify pain, physical function, and structure states that represent the progression from early to late disease for individuals with OA of the hip and knee,
The issue of factors predisposing for inhibitor development in haemophilia patients is still largely unresolved. In an attempt to address this problem, we initiated a registry in 1996 of siblings with haemophilia and with or without a history of inhibitors. Four hundred and sixty families have accrued, of whom 388 suffer from haemophilia A and 72 haemophilia B. Twenty-five of the brother pairs are
Redox chemistry is central to the primary functions of chloroplasts and mitochondria, that is, to energy conversion in photosynthesis and respiration. However, these bioenergetic organelles always contain very small, specialized genetic systems, relics of their bacterial origin. At huge cost, organellar genomes contain, typically, a mere 0.1% of the genetic information in a eukaryotic cell. There
The “acidic mantle” of the skin surface has been related to several essential functions of the skin, although the origin of the acidity is still obscure. In this paper, we investigate how different transport processes can influence the local proton concentration inside a membrane consisting of oriented lipid bilayers. This system is chosen as a simple model of the extracellular lipids in the upper
basement membrane (BM) assembly, which is required for pregastrulation development. Individual domains may have other functions, not necessarily structural. The cell binding C terminus of Lm {alpha}1 chain contains five Lm globular (LG) domains. In vitro, {alpha}1LG1–3 domains bind integrins, and {alpha}1LG4 binds dystroglycan, heparin, and sulfatides. A prevailing hypothesis is that {alpha}1LG4 i

Quality of life (QoL) assessment in children with coagulation disorders is a relatively unstudied area. While hemophilia-specific questionnaires (such as Haemo-QoL) are available, no instrument for children with idiopathic thrombocytopenic purpura (ITP) has been validated yet. A disease-specific questionnaire for children with ITP was therefore developed (ITP-QoL) in three phases: (a) a preparator
Background A main goal in nursing care of persons with chronic heart failure (HF) is to strengthen their health related quality of life (HRQoL). This presupposes knowledge about the relation between heart failure and HRQoL. Existing studies have shown incongruent results about whether HRQoL is affected differently depending on age or sex of elderly persons with chronic HF. Aim This study aimed
The use of electron probes for in situ imaging of solution phase systems has been a long held objective, largely driven by the prospect of atomic resolution of molecular structural dynamics relevant to chemistry and biology. Here, we present a nanofluidic sample cell with active feedback to maintain stable flow conditions for pathlengths varying from 45 nm to several 100 nm, over a useable viewing
Background: Serum protein profiles have been investigated frequently to discover early biomarkers for breast cancer. So far, these studies used biological samples collected at or after diagnosis. This may limit these studies' value in the search for cancer biomarkers because of the often advanced tumor stage, and consequently risk of reverse causality. We present for the first time pre-diagnostic
The electronic structure of strongly correlated systems is usually calculated by using an effective model Hamiltonian with a small number of states and an effective on-site interaction. The mode, however, neglects the frequency dependence of the interaction, which emerges as a result of dynamical screening processes not included in the model. The self-energy calculated in this kind of model within
This thesis investigates speech production and self-monitoring by using a newly constructed Real-time Speech Exchange (RSE) system. This system makes it possible to covertly manipulate the auditory feedback that participants receive of their own voice. First a word or utterance made by the participant is recorded, and later in the test this recording is inserted into their auditory feedback with p
Aim: This is the first study to evaluate compliance with the 2003 Swedish national guidelines for prophylactic treatment of respiratory syncytial virus (RSV) in children with congenital heart disease (CHD). We estimated the relative risk (RR) of children with CHD being hospitalised with a RSV infection, studied the extent to which RSV prophylactic treatment with palivizumab corresponded to the gui
A search for microscopic black holes has been performed in a same-sign dimuon final state using 1.3 fb(-1) of proton-proton collision data collected with the ATLAS detector at a centre of mass energy of 7 TeV at the CERN Large Hadron Collider. The data are found to be consistent with the expectation from the Standard Model and the results are used to derive exclusion contours in the context of a l
