Decreased Neutrophil Apoptosis in Quiescent ANCA-Associated Systemic Vasculitis.

BACKGROUND: ANCA-Associated Systemic Vasculitis (AASV) is characterized by leukocytoclasis, accumulation of unscavenged apoptotic and necrotic neutrophils in perivascular tissues. Dysregulation of neutrophil cell death may contribute directly to the pathogenesis of AASV. METHODS: Neutrophils from Healthy Blood Donors (HBD), patients with AASV most in complete remission, Polycythemia Vera (PV), Sy

CYTOGENETIC AND MOLECULAR GENETIC CHARACTERIZATION OF LIPOMAS

Popular Abstract in Swedish Cancer uppstår via genetiska förändringar som leder till ohämmad reglering av celltillväxt. Tumörer i mjukdelar utgör en grupp av solida tumörer, med över 100 histologiska typer. Mjukdelstumörer uppstår från mesenkymal vävnad, som inkluderar fett, bindväv, muskulatur, och det perifera nervsystemet. Mjukdelstumörer är en extremt heterogen grupp, både vad gäller morfologiThe focus of this thesis was to study cytogenetic and molecular genetic aberrations in lipomas. For this purpose, chromosome banding analysis, fluorescence in situ hybridization (FISH), as well as high resolution single nucleotide polymorphism (SNP)–arrays were used to identify recurrent chromosomal aberrations in lipomas. The possible molecular targets for these aberrations were further studied t

Non-Invasive Measures of Heart Failure

Popular Abstract in Swedish Hjärtsvikt är en sjukdom som beror på att hjärtat inte kan pumpa ut tillräckligt med blod till kroppens vävnader. I Sverige drabbas årligen 30000 personer av hjärtsvikt, och prognosen är jämförbar med de vanligaste cancerformerna. Trots att det är så vanligt och allvarligt, saknas i dagsläget objektiva mått på hjärtsvikt – det finns alltså ingen ”linjal” för att mäta huHeart failure is a clinical syndrome characterized by an inability of the heart to meet the metabolic demands of the body. Approximately 1-2% of the population in the western society has the diagnosis, and the 5-year mortality rate is comparable with the common cancer diagnoses. The lack of reliable objective measures of heart failure motivates research in this direction. Blood flow is an essentia

A Panel of Kallikrein Marker Predicts Prostate Cancer in a Large, Population-Based Cohort Followed for 15 Years without Screening

Background: Prostate-specific antigen (PSA) has modest specificity for prostate cancer. A panel of four kallikrein markers (total PSA, free PSA, intact PSA, and kallikrein-related peptidase 2) is a highly accurate predictor of biopsy outcome. The clinical significance of biopsy-detectable cancers in men classified as low-risk by this panel remains unclear. Methods: The Malmo Diet and Cancer study

Health-related quality of life in Swedish children and adolescents with limb reduction deficiency

Aim: To investigate health-related quality of life (HRQoL) in young persons with limb reduction deficiency (LRD). Methods: One hundred and forty children with LRD aged 8-16 answered the DISABKIDS questionnaire for children with chronic health conditions. Of their parents, 137 answered a corresponding questionnaire concerning their child. Results: Compared to reference data from children with other

A Pilgrimage to the Past : Johannes Bureus and the Rise of Swedish Antiquarian Scholarship, 1600-1650

At the end of the eighteenth century, Edward Gibbon described the antiquarian scholars of previous generations as men of “profound learning and easy faith.” His exemplar was the Swedish polymath Olof Rudbeck, who in a series of frantic and combative tomes sought to portray Sweden as the model for Plato’s Atlantis and the seething cultural cauldron from which Western civilization had emerged. A Pil

Making Food Protein Gels via an Arrested Spinodal Decomposition

We report an investigation of the structural and dynamic properties of mixtures of food colloid casein micelles and low molecular weight poly(ethylene oxide). A combination of visual observations, confocal laser scanning microscopy, diffusing wave spectroscopy, and oscillatory shear rheometry is used to characterize the state diagram of the mixtures and describe the structural and dynamic properti

Cooperation between gatekeepers in sickness insurance - the perspective of social insurance officers. A qualitative study.

ABSTRACT: BACKGROUND: Objective was to describe variations in how social insurance officers conceive the cooperation with the health care in their daily work with sick leave. METHODS: Fifteen social insurance officers (SIOs) working with administration of sickness benefits were interviewed. They were purposefully recruited to represent different parts of the social insurance office organization, d

Incidence of Lower Limb Amputation in the Diabetic and Nondiabetic General Population: A 10-year Population-based Cohort Study of Initial Unilateral, Contralateral and Re-amputations.

OBJECTIVE - The purpose of this study was to compare the incidence of vascular lower-limb amputation (LLA) in the diabetic and nondiabetic general population. RESEARCH DESIGN AND METHODS - A population-based cohort study was conducted in a representative Swedish region. All vascular LLAs (at or proximal to the transmetatarsal level) performed from 1997 through 2006 were consecutively registered an

System analysis of a PV/T hybrid solar window

A building-integrated multifunctional PV/T solar window was suggested and developed by Andreas Fieber. The solar window is constructed of PV cells laminated on solar absorbers placed in a window behind the glazing. To reduce the costs of solar electricity, tiltable reflectors have been introduced in the construction to focus radiation onto the solar cells. The reflectors make it possible to contro

A First-in-Man Study of the Reitan Catheter Pump for Circulatory Support in Patients Undergoing High-Risk Percutaneous Coronary Intervention

Objectives: To investigate the safety of a novel percutaneous circulatory support device during high-risk percutaneous coronary intervention (PCI). Background: The Reitan catheter pump (RCP) consists of a catheter-mounted pump-head with a foldable propeller and surrounding cage. Positioned in the descending aorta the pump creates a pressure gradient, reducing afterload and enhancing organ perfusio

Engineering Cofactor Preference of Ketone Reducing Biocatalysts: A Mutagenesis Study on a γ-Diketone Reductase from the Yeast Saccharomyces cerevisiae Serving as an Example

The synthesis of pharmaceuticals and catalysts more and more relies on enantiopure chiral building blocks. These can be produced in an environmentally benign and efficient way via bioreduction of prochiral ketones catalyzed by dehydrogenases. A productive source of these biocatalysts is the yeast Saccharomyces cerevisiae, whose genome also encodes a reductase catalyzing the sequential reduction of

Prediction of endometrial malignancy in women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm.

OBJECTIVE: To build mathematical models to evaluate the individual risk of endometrial malignancy in women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm using clinical data, sonographic endometrial thickness and power Doppler ultrasound findings. METHODS: Of 729 consecutive patients with postmenopausal bleeding, 261 with sonographic endometrial thickness ≥ 4.5 mm and

Exposure to Polybrominated Diphenyl Ethers and Male Reproductive Function in Greenland, Poland and Ukraine.

Animal and a few human studies suggest that polybrominated diphenyl ethers (PBDEs) may affect male reproductive function. The aim of the present study was to evaluate if male reproductive function was associated with serum level of PBDEs. We evaluated, in a cross-sectional study, the effects of environmental exposure to BDE-47 and BDE-153 on reproductive hormones and semen quality, including marke

A framework for regularized non-negative matrix factorization, with application to the analysis of gene expression data.

Non-negative matrix factorization (NMF) condenses high-dimensional data into lower-dimensional models subject to the requirement that data can only be added, never subtracted. However, the NMF problem does not have a unique solution, creating a need for additional constraints (regularization constraints) to promote informative solutions. Regularized NMF problems are more complicated than conventio
