Evolution of DC-SIGN use revealed by fitness studies of R5 HIV-I variants emerging during AIDS progression

Background: At early stages of infection CCR5 is the predominant HIV-1 coreceptor, but in approximately 50% of those infected CXCR4-using viruses emerge with disease progression. This coreceptor switch is correlated with an accelerated progression. However, those that maintain virus exclusively restricted to CCR5 (R5) also develop AIDS. We have previously reported that R5 variants in these "non-sw

Is it possible to predict the outcome of an anterior cruciate ligament injury?

This thesis centers on a well-studied cohort of 100 patients, which received a treatment regimen of initial rehabilitation and activity modification to cope with Anterior Cruciate Ligament (ACL) injury. The data, collected prospectively and longitudinally, cover a span of 15 years after initial injury. The overall aim of this thesis is to describe the course of an ACL injury treated with rehabilit

Patients with ankylosing spondylitis have increased sick leavea registry-based casecontrol study over 7 yrs

Objectives. Using prospectively collected registry data to investigate sick leave (sickness benefit and sickness compensation) over a 7-yr period in patients with AS in comparison with population-based controls matched for age, sex and residential area. Methods. We investigated 122 (21 women and 101 men) outpatients with AS in South Sweden, born 1942 or later, from rheumatology specialist care for

Safety and tolerability of intracerebroventricular PDGF-BB in Parkinson's disease patients

BACKGROUND. Recombinant human PDGF-BB (rhPDGF-BB) reduces Parkinsonian symptoms and increases dopamine transporter (DAT) binding in several animal models of Parkinson's disease (PD). Effects of rhPDGF-BB are the result of proliferation of ventricular wall progenitor cells and reversed by blocking mitosis. Based on these restorative effects, we assessed the safety and tolerability of intracerebrove

Twelve type 2 diabetes susceptibility loci identified through large-scale association analysis

By combining genome-wide association data from 8,130 individuals with type 2 diabetes (T2D) and 38,987 controls of European descent and following up previously unidentified meta-analysis signals in a further 34,412 cases and 59,925 controls, we identified 12 new T2D association signals with combined P < 5 x 10(-8). These include a second independent signal at the KCNQ1 locus; the first report, to

A visual field index for calculation of glaucoma rate of progression.

PURPOSE: To present a new perimetric index for calculating the rate of glaucomatous progression and to compare its performance with the traditional mean deviation index (MDI). DESIGN: Experimental study describing a device and retrospective cohort study. METHODS: We developed a new visual field index, the glaucoma progression index (GPI), intended to be less affected by cataract than the MDI by ca

Physicochemical Characterization of Simulated Intestinal Fed-State Fluids Containing Lyso-Phosphatidylcholine and Cholesterol

An array of simulated intestinal fed-state fluids, where phosphatidylcholine (PC) was replaced by lysophosphatidylcholine (LPC) and cholesterol (Chol) was added, were visualized with Cryogenic Transmission Electron Microscopy (Cryo-TEM). Micelles were the dominating structural features, emphasizing the micellar-forming characteristics of LPC. Upon increase of the monoglyceride (MG) level, unilamel

A Paradigm Shift in George Berkeley's Philosophy 1707-1709

In this paper, I argue that there is a paradigm shift in George Berkeley's philosophy between his early unpublished manuscripts (1707-1708) and the Theory of Vision (1709). If so, the traditional method of mixing published and unpublished material will lead to a confused picture of both his early, unpublished view and the doctrine that lie published.

Ciliary neurotrophic factor has intrinsic and extrinsic roles in regulating B cell differentiation and bone structure.

The gp130 receptor and its binding partners play a central role in cytokine signalling. Ciliary neurotrophic factor (CNTF) is one of the cytokines that signals through the gp130 receptor complex. CNTF has previously been shown to be a negative regulator of trabecular bone remodelling and important for motor neuron development. Since haematopoietic cell maintenance and differentiation is dependent

Developments in Swedish forest policy and administration – from a 'policy of restriction' towards a 'policy of cooperation'

New tools and forms of cooperation at the landscape level are needed in order for forestry and environmental conservation to co-exist in areas with many land owners. Awareness has existed for several years in Sweden that cooperation at the landscape level is essential for protecting areas of high environmental value. This awareness has come to expression in several projects and initiatives. One of

Anisotropic Eliashberg function and electron-phonon coupling in doped graphene

We investigate, with high-resolution angle-resolved photoemission spectroscopy, the spectral function of potassium-doped quasi-free-standing graphene on Au. Angle-dependent x-ray photoemission and density functional theory calculations demonstrate that potassium intercalates into the graphene/Au interface, leading to an upshift of the K-derived electronic band above the Fermi level. This empty ban

Outcome of physiotherapy after surgery for cervical disc disease: a prospective randomised multi-centre trial

Background: Many patients with cervical disc disease require leave from work, due to long-lasting, complex symptoms, including chronic pain and reduced levels of physical and psychological function. Surgery on a few segmental levels might be expected to resolve disc-specific pain and reduce neurological deficits, but not the non-specific neck pain and the frequent illness. No study has investigate

A New Simulation Package to Model Detector Systems with Fragmentation Reactions and Ion Separators: Application to the LYCCA-0 System

A Monte-Carlo simulation package has been developed to model the response of a detector system for ion identification used in conjunction with ion separators following nuclear reactions. The simulation is written predominantly using the GEANT4 framework but utilises the ion transport code MOCADI for accurate separator and reaction modelling. A novel MOCADI-GEANT4 interface has been developed to ut

Fri rörlighet för familjer - en normativ analys av föräldrapenningen och EU-rätten

Popular Abstract in Swedish Att det ska råda fri rörlighet för arbetstagare/personer och deras familjemedlemmar är en grundläggande princip i EU-rätten. I artikel 48 i Fördraget om Europeiska unionens funktionssätt (EUF) ges EU befogenhet att vidta åtgärder för att koordinera, samordna, de olika nationella sociala trygghetssystemen inom EU. Förordning 1408/71 och dess ersättare förordning 883/2004This doctoral thesis examines the Swedish parental benefit in relation to the EU principles on free movement, namely the Treaty provisions on free movement for workers and Union citizens, and more specifically, the legislation on coordination of social security benefits – Regulation 1408/71 and its successor Regulation 883/2004. The rights enshrined in the Treaty on the Functioning of the European

NMR diffusion and relaxation correlation methods: New insights in heterogeneous materials

Heterogeneous materials, such as biological tissues, foodstuffs, and rocks, contain a range of microscopic environments where the molecular constituents often have different NMR relaxation time constants and self-diffusion coefficients. Multidimensional correlation methods have greatly improved the possibility for separating and assigning the NMR responses from distinct environments, thereby allow

Living with cancer and perception of care: Icelandic oncology outpatients, a qualitative study

Aim This qualitative study was set out to explore oncology outpatient experiences of having cancer, to illuminate coping strategies and to explore perceptions of care and service provided while treated for cancer. Materials and methods Thirty patients undergoing chemotherapy or radiotherapy were consecutively selected for the study in three oncology outpatient clinics in Iceland; mean age was 55 y
