Round to elongate microbodies associated with fossil vertebrate soft tissues were interpreted as microbial traces until 2008, when they were re-described as remnant melanosomes - intracellular, pigment-containing eukaryotic organelles. Since then, multiple claims for melanosome preservation and inferences of organismal color, behavior, and physiology have been advanced, based upon the shape and si
Leukocyte accumulation is a rate-limiting step in inflammatory lung injury. The aim of this study was to define the role of CD11a/CD18 and CD11b/CD18 in sepsis-induced leukocyte rolling and adhesion in lung arterioles, capillaries and venules in male C57BL/6 mice using intravital fluorescence microscopy. Cecal ligation and puncture (CLP) markedly increased leukocyte rolling in arterioles and venul
Purpose: To validate the Swedish version of the Distress Thermometer (DT) against the Hospital Anxiety and Depression Scale (HADS) for screening of distress and to explore how well DT measures changes of distress during six months in a population of heterogeneous oncology patients. Methods: The DT was translated into Swedish according to the forward- and back-translation procedure. HADS total scor
Names of taxa referred to Hieracium sect. Alpestria (including the ‘Semidovrensia group’), Foliosa and Prenanthoidea and reported from Sweden have been compiled from the literature and herbaria and all uses have been indexed. Based on this synopsis, the nomenclatural validity and legitimacy of the names are analysed. In total, the use of 75, 62 and 27 names is documented for the three sections, re
A study was undertaken to measure the efficiency with which carbon dioxide was stripped from freshwater (0 parts per thousand) and saline water (35 parts per thousand NaCl) passing through an air-lift at 15 degrees C. The air-lift was constructed of 50 mm (OD) PVC pipe submerged 95 cm in a tank, had an adjustable air injection rate, and could be adjusted to three lifting heights: 11,16 and 25 cm.
Inresource-constrained systems, the interference generated by the concurrent execution of multiple controller tasks leads to extra delay and jitter, which degrade control performance and may even jeopardize the stability of the controlled system. This work presents a general methodology that integrates control issues and real-time schedulability analysis to improve the control performance in embed
The photochemical oxidation of oceanic dissolved organic carbon (DOC) to carbon monoxide (CO) and carbon dioxide (CO2) has been estimated to be a significant process with global photoproduction transforming petagrams of DOC to inorganic carbon annually. To further quantify the importance of these two photoproducts in coastal DOC cycling, 38 paired apparent quantum yield (AQY) spectra for CO and CO
Heart Rate Variability and Irregularity During AF IntroductionIrregularity measures have been suggested as risk indicators in patients with atrial fibrillation (AF); however, it is not known to what extent they are affected by commonly used rate-control drugs. We aimed at evaluating the effect of metoprolol, carvedilol, diltiazem, and verapamil on the variability and irregularity of the ventricula
The purpose of this article is to argue for a position holding that epigenetic responsibility primarily should be a political and not an individual responsibility. Epigenetic is a rapidly growing research field studying regulations of gene expression that do not change the DNA sequence. Knowledge about these mechanisms is still uncertain in many respects, but main presumptions are that they are tr
Microglia manage immunosurveillance and mediate inflammation, both suggested to be important in Alzheimer's disease (AD). The aim of this study was to investigate if microglial markers could differentiate, firstly between AD and controls, and secondly between stable mild cognitive impairment (MCI) and those progressing to AD and vascular dementia (VaD). Furthermore, we investigated if these marker
Objective: To determine the usefulness and prognostic value of a simplified salivary gland ultrasonography (SGUS) scoring system in primary Sjögren's syndrome (pSS). Methods: Patients with pSS (n=105) and controls (n=57) were evaluated using a simplified SGUS scoring system. Parenchymal homogeneity in salivary glands was graded from 0 to 3, grades 0 (normal) and 1 (mild inhomogeneity) being interp
Dronedarone is a strong P-glycoprotein inhibitor with a potential to increase bioavailability of dabigatran. We sought to measure and report plasma concentrations of dabigatran in patients with atrial fibrillation (AF) on concomitant dronedarone treatment.
Impact of Bi incorporation into (Ga,Mn)As layers on their electronic-and band-structures as well as their magnetic and structural properties has been studied. Homogenous (Ga,Mn)(Bi,As) layers of high structural perfection have been grown by the low-temperature molecular-beam epitaxy technique. Post-growth annealing treatment of the layers results in an improvement of their structural and magnetic
The importance of the home environment increases with age. Perceived aspects of home influence life satisfaction, perceived health, independence in daily activities and well-being among very old people. However, research on health and perceived aspects of home among senior citizens in earlier phases of the aging process is lacking. Therefore, the main aim was to explore whether perceived aspects o
Projections of vegetation distribution that incorporate the transient responses of vegetation to climate change are likely to be more efficacious than those that assume an equilibrium between climate and vegetation. We examine the non-equilibrium dynamics of a temperate forest region under historic and projected future climate change using the dynamic ecosystem model LPJ-GUESS. We parameterized LP
A photofragmentation laser-induced fluorescence (PF-LIF) technique was applied to an HCCI engine for hydrogen peroxide (H2O2) measurements. A pump-probe strategy was adopted with the pump laser (266 nm) photolyzing H2O2, and with the probe laser (283 nm) detecting the generated OH photofragments. An on-line calibration process was performed by introducing a known amount of vaporized H2O2/water sol
Aerobic granulation is increasingly used in wastewater treatment due to its unique physical properties and microbial functionalities. Granule size defines the physical properties of granules based on biomass accumulation. This study aims to determine the profile of size development under two physicochemical conditions. Two identical bioreactors namely Rnp and Rp were operated under non-phototrophi
MafA is a key transcriptional activator of islet beta cells and its exclusive expression within beta cells of the developing and adult pancreas is distinct amongst pancreatic regulators. Region 3 (base pairs -8118/-7750 relative to the transcription start site), one of six conserved 5' cis-domains of the MafA promoter, is capable of directing beta-cell-line-selective expression. Transgenic reporte
Poly(3-hydroxypropionate), P(3HP), is a polymer combining good biodegradability with favorable material properties. In the present study, a production system for P(3HP) was designed, comprising conversion of glycerol to 3-hydroxypropionaldehyde (3HPA) as equilibrium mixture with 3HPA-hydrate and -dimer in aqueous system (reuterin) using resting cells of native Lactobacillus reuteri in a first stag
