To validate an automatic algorithm for offline T2* measurements, providing robust, vendor-independent T2*, and uncertainty estimates for iron load quantification in the heart and liver using clinically available imaging sequences.

Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a group of autoimmune diseases, including granulomatosis with polyangiitis (GPA) and microscopic polyangiitis (MPA). It is not known why ANCA develop, but it has been shown that they participate in pathogenesis by activating polymorphonuclear neutrophils (PMNs). In this study we hypothesize that dysregulation of phagocytosi

The extracellular matrix consists of structural macromolecules and other proteins with regulatory functions. An important family of the latter class of molecules found in most tissues is the small leucine-rich repeat proteins (SLRPs). We have previously shown that the SLRP fibromodulin binds directly to C1q and activates the classical pathway of complement. In the present study we further examine

The gene for Vitreoscilla hemoglobin (VHb) has been introduced and expressed in Nicotiana tabaccum (tobacco). Transgenic tobacco plants expressing VHb exhibited enhanced growth, on average 80-100% more dry weight after 35 days of growth compared to wild-type controls. Furthermore, germination time is reduced from 6-8 days for wild-type tobacco to 3-4 days and the growth phase from germination to f

Background: At present a majority of older people remain in their ordinary homes. Research has generated knowledge about home and health dynamics and increased the awareness of the complexity of housing as related to ageing. As this knowledge is based mainly on research on very old, single-living people in ordinary housing there is a need to study other sub-groups of the ageing population. Thus, t

Background: Chronic pain is common in older adults, yet little is known of its development in old age. Although fear-avoidance beliefs in chronic pain have been explored in younger adults, the relationship between chronic pain, kinesiophobia and physical activity levels has not been investigated in older adults.Objectives: The overall aim was to explore prevalence, development and related factors

To estimate intraobserver repeatability and interobserver agreement in assessing the presence of papillary projections in adnexal masses and in classifying adnexal masses using the International Ovarian Tumor Analysis (IOTA) terminology for ultrasound examiners with different levels of experience, to identify ultrasound findings that cause confusion and might be interpreted differently by differen

Background. We report a case of patient-to-surgeon transmission of hepatitis C virus (HCV), and the subsequent transmission of HCV to surgical patients. Methods. In 2007, a cardiac surgeon tested positive for hepatitis C. A complete look-back investigation was initiated that involved screening of all patients on the surgeon's operating lists between September 2004 and April 2007. Genotyping and ph

High-throughput multiplexed protein quantification using mass spectrometry is steadily increasing in popularity, with the two major techniques being data-dependent acquisition (DDA) and targeted acquisition using selected reaction monitoring (SRM). However, both techniques involve extensive data processing, which can be performed by a multitude of different software solutions. Analysis of quantita

Tuberculosis, is caused by various strains of Mycobacteria, and specifically the one by Mycobacterium tuberculosis needs effective treatment. Administration of antibiotics fails owing to multi-drug resistant capability of Mycobacterium. Traditional methods for the identification of a potential drug take time and require huge investment The present study was focused on virtual screening to identify

Background/Aims: The incidence of lectin allergic disease is increasing in recent decades, and definitive treatment is still lacking. Identification of B and T-cell epitopes of allergen will be useful in understanding the allergen antibody responses as well as aiding in the development of new diagnostics and therapy regimens for lectin poisoning. In the current study, we mainly addressed these que

This year the Swedish Society of Medicineand Lund Society of Medicine have arranged aBerzelius Symposium in Malmo¨/Lund on September24–26, 2008. This is the 1st InternationalSymposium in Sweden on The AgingMale.The purpose is to bring together scientistsand clinicians in this relatively new disciplineto highlight, in a multidisciplinary setting, thecauses and consequences of male aging and itssoci

Access to metabolic information in vivo using magnetic resonance (MR) technologies has generally been the niche of MR spectroscopy (MRS) and spectroscopic imaging (MRSI). Metabolic fluxes can be studied using the infusion of substrates labeled with magnetic isotopes, with the use of hyperpolarization especially powerful. Unfortunately, these promising methods are not yet accepted clinically, where

While there is ongoing discussion about the details of implementation of whole genome sequencing (WGS) and whole exome sequencing (WES), there appears to be a consensus amongst geneticists that the widespread use of these approaches is not only inevitable, but will also be beneficial [1]. However, at the present time, we are unable to anticipate the full range of uses, consequences and impact of i

This work presents a data-driven model to simulate the mechanical behavior of the breast tissues in real time. The aim of this model is to speed up some multimodal registration algorithms, as well as some image-guided interventions. Ten virtual breast phantoms were used in this work. Their deformation during a mammography was performed off-line using the finite element method. Three machine learni

Pathogens that invade the human host are confronted by a multitude of defence mechanisms aimed at preventing colonization, dissemination and proliferation. The most frequent outcome of this interaction is microbial elimination, in which the complement system plays a major role. Complement, an essential feature of the innate immune machinery, rapidly identifies and marks pathogens for efficient rem
