This paper reports on the geochemistry of the mid-Silurian Grotlingbo Bentonite, a ca. 0.10.4-m-thick and regionally important bentonite bed in Sweden and the East Baltic area. A series of eight samples, spaced by 5cm, were taken from the Hunninge-1 drillcore in Gotland, Sweden, and were analysed in order to establish the vertical element composition and variation in the bentonite. The results sho
Therapy with i.v. iron in patients with chronic heart failure (CHF) and iron deficiency (ID) improves symptoms, functional capacity, and quality of life. We sought to investigate whether these beneficial outcomes are independent of anaemia. FAIR-HF randomized 459 patients with CHF [NYHA class II or III, LVEF 40 (NYHA II) or 45 (NYHA III)] and ID to i.v. iron as ferric carboxymaltose (FCM) or place
To examine the potential influence of terrestrially derived DOM on the Baltic Sea, a year-long study of dissolved organic matter (DOM) was performed in three river catchments in Sweden. One catchment drains into the Bothnian Sea, while two southern catchments drain into the Baltic proper. Dissolved organic carbon (DOC) concentrations were positively correlated with discharge from forested catchmen
Using X-ray photoelectron spectroscopy we studied the coadsorption of the amino acid l-cysteine and gold on a rutile TiO(2)(110) surface under ultrahigh vacuum conditions. Irrespective of the deposition order, i.e., irrespective of whether l-cysteine or gold is deposited first, the primary interaction between l-cysteine and the gold clusters formed at the surface takes place through the deprotonat
The Sao Francisco Craton (SFC) is an Archaean-Proterozoic craton that hosts a significant number of mafic intrusions. Previous attempts to date the igneous emplacement of these rocks are limited to a few poor precision Rb-Sr and Sm-Nd isochrons. Here, dykes from the Curaca belt, in the northeastern portion of the craton, as well as from the Chapada Diamantina region in the central part, were dated
Whole-body ischemia during out-of-hospital cardiac arrest triggers immediate activation of inflammatory systems leading to a sepsis-like syndrome. The aim was to investigate the association between level of systemic inflammation and mortality in survivors after out-of-hospital cardiac arrest treated with targeted temperature management.
Purpose: This study explores the implications for cancer induction of treatment details such as fractionation, planning target volume (PTV) definition, and interpatient variations, which are relevant for the radiation treatment of prostate carcinomas. Methods and Materials: Treatment planning data from 100 patients have been analyzed with a risk model based on the United Nations Scientific Committ
It is believed that the effectiveness of colloids as plasma volume expanders is dependent on the endothelial permeability for macromolecules. The objective of this study was to test the hypothesis that the plasma volume expanding effect of 5% albumin relative to that of a crystalloid solution is reduced if microvascular permeability is increased.
Background: Mastery refers to the degree to which people perceive that they can control factors that influence their life situation, and has been found important for people's quality of life and well-being. It is thus essential to be able to measure mastery in a valid and reliable way. Aim: This study aimed at using the Rasch measurement model to investigate the psychometric properties of a Swed
A series of copoly(arylene ether sulfone)s having precisely two, three or four quaternary ammonium (QA) groups clustered directly on single phenylene rings along the backbone are studied as anion exchange membranes. The copolymers are synthesized via condensation polymerizations involving either di-, tri- or tetramethylhydroquinone, followed by virtually complete benzylic bromination using N-bromo
The paper develops an analytical framework for understanding the role of social media in the 2011 North African uprisings. It argues that analysis of the role of Facebook, Twitter, and other social media tools should be broken down into two distinct phases: a pre-mobilisation phase and a collective action phase. Using frame analysis and the notion of connective action, the paper demonstrates that
The article is intended to give a short overview of epidemiological data on cancer risks associated with very low absorbed doses of ionising radiation. The linear no-threshold (LNT) approach to estimate cancer risks involves the use of epidemiological data at higher doses (>100 mSv), but is supported by data from lower exposure of more sensitive population groups like fetuses and children and the
Purpose : To evaluate the association between the Society for Vascular Surgery/American Association for Vascular Surgery (SVS/AAVS) anatomical severity grading (ASG) score and operative outcomes in fenestrated endovascular repair (f-EVAR) for juxtarenal aortic aneurysm. Methods : A review was conducted of all patients treated at our clinic with commercially available, custom-made f-EVAR devices be
Genetically polymorphic species offer the possibility to study maintenance of genetic variation and the potential role for genetic drift in population divergence. Indirect inference of the selection regimes operating on polymorphic traits can be achieved by comparing population divergence in neutral genetic markers with population divergence in trait frequencies. Such an approach could further be
The aim of the present animal study was to examine the anti-hypertensive capacity of two probiotic products combining blueberries and the tannase producing probiotic bacteria Lactobacillus plantarum DSM 15313 and to investigate if such an effect is linked to a change in the gut microbiota.
Background: Climate change affects human health in various ways. Health planners and policy makers are increasingly addressing potential health impacts of climate change. Ethiopia is vulnerable to these impacts. Assessing students' knowledge, understanding and perception about the health impact of climate change may promote educational endeavors to increase awareness of health impacts linked to cl
Several studies on the use of erythropoietin (Epo) to treat anaemia in patients undergoing cancer treatment have shown adverse effects on tumour control and survival. Experimental studies indicate that this could be linked to an interaction with wound healing processes and not an effect on tumour cells per se. We have previously shown that erythropoietin in combination with surgical trauma stimula
