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

Background: We have developed an in vitro model by organ culture of rat mesenteric arteries to imitate vascular smooth muscle cell (VSMC) receptor changes in cardiovascular disease. By using this model, alteration of VSMC thromboxane A(2) (TP) receptors was studied. Methods and Results: After organ culture of the arteries, VSMC TP receptors were studied by using myography, real-time PCR and immuno

Popular Abstract in Italian Con il termine aterosclerosi si usa generalmente definire uno stato di infiammazione cronica che risulta nella riduzione di elasticita´ delle pareti dei vasi arteriori di medio e grande diametro. La lesione caratteristica dell´aterosclerosi e´ l´ateroma, o placca aterosclerotica, ossia un´ispessimento dello strato piu´ interno delle arterie. Le placche cominciano a formCardiovascular (CV) atherosclerotic diseases are the leading cause of death in Western nations. The presence of a carotid plaque, the degree of carotid stenosis as well as the rate of progression of carotid disease has been shown to be independent predictive factors for future ischemic events. The aim of this thesis was to detect clinical, sonographic and serologic patterns that could aid in ident

One option for coping with wasteful uses of fresh water in landscape irrigation is to use the treated greywater(GW). In the present study, an evaluation of a simple treatment system for reusing GW to irrigate green areas,trees, and ornamentals all over the campus in Tafila Technical University (TTU), Jordan, is presented. After 12 months of using the treatment system, the necessity for using fresh

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

The diffractive process ep -> eXY, where Y denotes a proton or its low mass excitation with M-Y < 1.6 GeV, is studied with the H1 experiment at HERA. The analysis is restricted to the phase space region of the photon virtuality 3 <= Q(2) <= 1600 GeV2, the square of the fourmomentum transfer at the proton vertex vertical bar t vertical bar < 1.0 GeV2 and the longitudinal momentum fraction of the in

In this paper, we are concerned with the construction and analysis of high order exponential splitting methods for the time integration of abstract evolution equations which are evolved by analytic semigroups. We derive a new class of splitting methods of orders three to fourteen based on complex coefficients. An optimal convergence analysis is presented for the methods when applied to equations o

This study aims to assess the effect of radiation treatment on the tumour vasculature and its downstream effects on hypoxia and choline metabolism using a multimodal approach in the murine prostate tumour model CWR22. Functional parameters derived from Positron Emission Tomography (PET)/Computer Tomography (CT) with (18)F-Fluoromisonidazole ((18)F-FMISO) and (18)F-Fluorocholine ((18)F-FCH) as well

The complex genetics of cancer, which allows tumours to grow and spread while bypassing the control circuitry of the cell, involves dysregulation of the genome, transcriptome and proteome. The importance of protein-coding genes such as growth factors and hormone receptors is well established. Recently, non-coding RNAs have emerged as important players in tumour development with potential to be exp

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

ObjectivesIn this follow-up study, we wanted to present the long-term outcome (5-21years) in terms of seizure freedom, seizure reduction, and the cognitive development in the first 47 children who underwent epilepsy surgery at the University Hospital in Lund from 1991 to 2007. Materials and methodsAll children who underwent epilepsy surgery in the southern region of Sweden were assessed for cognit

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

The purpose of this thesis is to explore the prevalence of sexually offending behaviour among female and male adolescents in Sweden. One aim is to identify potential risk factors associated with sexually offending behaviour and a further aim to examine the outcome in early adulthood for a sample of sexually offending adolescent males. Three different samples were used for this thesis. A sample of

The most common cancer treatments currently available are radio- and chemo-therapy. These therapies have, however, drawbacks, such as, the reduction in quality of life and the low efficiency of radiotherapy in cases of multiple metastases. To lessen these effects, we have encapsulated an anti-cancer drug into a biocompatible matrix. In-vitro assays indicate that this bio-nanocomposite is able to i

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

In order to influence every day clinical practice professional organisations issue management guidelines. Cross-sectional surveys are used to evaluate the implementation of such guidelines. The present survey investigated screening for glucose perturbations in people with coronary artery disease and compared patients with known and newly detected type 2 diabetes with those without diabetes in term

In this paper, we demonstrate how to take advantage of the large number of spatial samples provided by commercial multispectral RGB imagers. We investigate the possibility to use various multidimensional histograms and probability distributions for decomposition and predictive models. We show how these methods can be used in an example using images of different Skyros wall lizards and demonstrate

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

Life is polymeric in its essence. The living cell contains a range of biopolymers such as proteins, carbohydrates, and nucleic acids. The cells are often compartmentalized via membranes that are composed of lipids. These are small molecules, but they spontaneously aggregate into supermolecular structures. The building blocks of these lipids are among others fatty acids, structures built from methy

Question: Under what circumstances are local communities and metacommunities phylogenetically clustered, overdispersed or random assemblages in terms of phylogenetic relatedness? Methods: An individual-based eco-evolutionary model was used to explain the link between system properties, ecological and evolutionary processes, and phylogenetic patterns in a spatially explicit competitive metacommunit
