Mortality rates and risk factors for asymptomatic deep vein thrombosis in medical patients

The clinical importance of asymptomatic proximal and distal deep vein thrombosis (DVT) remains uncertain and controversial. The aim of this retrospective, post-hoc analysis was to examine mortality and risk factors for development of proximal DVT in hospitalized patients with acute medical illness who were recruited into a randomized, prospective clinical trial of thromboprophylaxis with daltepari

The FERRUM Project: Experimental oscillator strengths of the UV 8 multiplet and other UV transitions from the y6P levels of Fe II

We report on experimental branching fractions (BFs) for 19 transitions from the three 3d 5( 6S)4s4p( 3P) y6P levels in Fe II, measured in Fourier transform spectra of a Penning discharge lamp and a hollow cathode lamp. The transition wavelengths span the interval between 1600 and 2850 Å. Absolute oscillator strengths ( f-values) have been derived by combining the BFs with experimental radiative li

Stimulation of nitrogen-fixing cyanobacteria in a Baltic Sea plankton community by land-derived organic matter or iron addition

In the Baltic Sea, floating blooms of nitrogen-fixing cyanobacteria occur yearly during late summer. These blooms can sometimes be limited by iron. Due to extensive foresting around the Baltic Sea, iron is entering the Baltic Sea partly bound to dissolved organic material (DOM) via rivers. An experiment was performed in 300 1 laboratory mesocosms to test the hypothesis that riverine high-molecular

The coupling between disulphide status, metallation and dimer interface strength in Cu/Zn superoxide dismutase

The gain of neurotoxic function in amyotrophic lateral sclerosis (ALS) has been linked to misfolding of the homodimeric enzyme Cu/Zn superoxide dismutase (SOD). Here, we present the crystal structure of fully cysteine-depleted human SOD (SOD (CallA)), representing a reduced, marginally stable intermediate on the folding pathway in vivo that has also been implicated as neurotoxic precursor state. A

Are associations between socio-economic characteristics and exposure to air pollution a question of study area size? An example from Scania, Sweden

BACKGROUND: Numerous studies have shown that exposure to air pollutants in the area of residence and the socio-economic status of an individual may be related. Therefore, when conducting an epidemiological study on the health effect of air pollution, socio-economy may act as a confounding factor. In this paper we examine to what extent socio-economic status and concentrations of NO2 in the county/

Plasma lipids and lipoproteins in subtypes of stroke

We determined plasma lipid and lipoprotein concentrations in 131 patients (95 males, 36 females, mean age 71 years) 6 months after acute stroke onset. Compared to a reference population, the alterations of plasma lipid concentrations in stroke patients were moderate. However, the stroke patients had higher levels of triglyceride and lipoprotein (a) and lower concentrations of cholesterol, high den

En metod för mätning av fuktprofiler i betongkonstruktioner : experimentell utvärdering av OE-metoden

Den övergripande målsättningen med projektet har varit att utifrån en prototyp av OE-staven ta fram ett fungerande mätsystem som håller jämförbar standard med dagens RF-mätningar. OE-metoden har visat sig uppfylla dessa krav och samtidigt vara ett kraftfullt verktyg för mätningar av RF-profiler i betongkonstruktioner. OE-metoden lämpar sig bäst att användas i svårbemästrade mätsituationer samt i s

Effects of hydrogen peroxide on the guinea-pig tracheobronchial mucosa in vivo

Lumenal entry of plasma (mucosal exudation) is a key feature of airway inflammation. In airways challenged with histamine-type mediators and allergen the mucosal exudation response occurs without causing epithelial derangement and without increased airway absorption. In contrast, reactive oxygen metabolites may cause mucosal damage. In this study, involving guinea-pig airways, we have examined eff

Determination of transition matrices for inhomogeneous dielectric bodies by a wave propagator method

A method for determining transition matrices for inhomogeneous dielectric shells is presented. The source can be either inside or outside the shell. The method is based upon expansions of the electric and magnetic fields in vector spherical harmonics. The expansion coefficients in the shell satisfy a system of linear ordinary differential equations in the radial direction. The expansion coefficien

How representative are clinical study patients with asthma or COPD for a larger "real life" population of patients with obstructive lung disease?

Evidence-based medicine is a corner stone in treatment decision making and large randomised, clinical trials are usually designed in order-to provide highly significant results. This study was conducted in order to find out to what extend a "real life" patient population with obstructive lung disease could fit into criteria commonly used in clinical research trials. As a secondary aim of the study

Caloplaca scutica, a new species from southern Ukraine.

Caloplaca sqtthfca Khodosovtsev & Sschting is described from Ukrainian Artemisia - Festuca steppes near the Black Sea. It grows on twigs of small shrubs of Halocnemum strobilaceum and Limonium sp.on salty soils, and is characterued by greenish grey areoles or squamules with punctiform to confluent soralia and zeorine apothecia with a conspicuous white pruina.

A SU-8 dish for cell irradiation

The objective of the CELLION project is radiation research at low doses. The main cell responses to low dose irradiation are bystander effects, genomic instability and adaptive responses. In order to study these effects it is convenient to make the cells addressable in space and time through locking the cell position. A new alternative dish has been developed for irradiation procedures at the Lund

DEAF SIGN LANGUAGE USERS - Prevalence and Aspects of Quality of Life in Old Age

Popular Abstract in Swedish Under de senaste åren har nödvändigheten att ta hänsyn till utsatta grupper i den svenska befolkningen och deras varierande behov lyfts fram i rapporter och utredningar om utformningen av vård och rehabilitering av äldre. En sådan utsatt grupp är äldre teckenspråkliga döva. Svårigheten att kommunicera, i kombination med åldersrelaterade sjukdomar, funktionsbegränsningarVery little is known about the consequences of aging and the wellbeing of deaf sign language users. This thesis contributes to filling this knowledge gap. The overarching aim was to gain further understanding and to increase the knowledge about quality of life, in terms of subjective wellbeing and health, activity and social contacts, among older deaf sign language users. After having established

Making the Most of It? : Understanding the social and productive dynamics of small farmers in semi-arid Iringa, Tanzania

Popular Abstract in Swedish Att klara sig trots allt: Den sociala och produktiva dynamiken hos småbönderna i de halvtorra områdena i Iringa i norra Tanzania. Det är inte lätt att överleva som småbonde i de halvtorra områdena i Iringa och på liknande platser i Afrika. Man kontrollerar knappast sin egen livssituation. Regnen är opålitliga, priser, marknadsföring och politiska ingrepp är oförutsägbaWhile much of semi-arid Africa is still sparsely populated with unused land, there are everywhere pockets of high and increasing population density in attractive locations. Small-scale farmers can respond to beginning land-scarcity in a number of ways. Through migration, through diversification of livelihoods, or through changes in their farming system. Which solution is chosen, depends not only o

Cloning, expression, characterisation and three-dimensional structure determination of Caenorhabditis elegans spermidine synthase

The polyamine synthesis enzyme spermidine synthase (SPDS) has been cloned from the model nematode Caenorhabditis elegans. Biochemical characterisation of the recombinantly expressed protein revealed a high degree of similarity to other eukaryotic SPDS with the exception of a low affinity towards the substrate decarboxylated S-adenosylmethionine (K-m = 110 mu M) and a less pronounced feedback inhib
