We hypothesized that treating distal radius fractures with cast only or closed reduction and cast is associated with high malunion risk and that the risk is higher in patients with low bone mineral density (BMD).
The dissociation behavior of proton conducting sulfonated polysulfones has been investigated by combining electrophoretic NMR, pulsed magnetic field gradient NMR and conductivity meas- urements on monomeric and polymeric samples with concentrations of ionic groups in the range where dissociation is not complete (IEC = 4.55 – 7.04 meq g-1). In this regime, counterion con- densation is shown to crit
The combustion timing in internal combustion engines affects the fuel consumption, in-cylinder peak pressure, engine noise and emission levels. The combination of an in-cylinder pressure sensor together with a direct injection fuel system lends itself well for cycle-to-cycle control of the combustion timing. This paper presents a method of controlling the combustion timing by the use of a cycle-t
Purpose – The purpose of this paper is to investigate how nurses’ working in emergency health care in Sweden experience their encounter with undocumented migrants. Design/methodology/approach – A total of 16 qualitative interviews were conducted and analyzed using a phenomenographic approach, aiming at describing various ways in which nurses experienced undocumentedness. Findings – The process of
Limited epidemiological evidence suggests a protective role for plant foods rich in flavonoids and antioxidants in hepatocellular cancer (HCC) etiology. Our aim was to prospectively investigate the association between dietary intake of flavonoids, lignans and nonenzymatic antioxidant capacity (NEAC) and HCC risk. Data from the European Prospective Investigation into Cancer and Nutrition (EPIC) coh
In this study, nickel pattern electrodes were electrochemically investigated in a three-electrode setup, operating both with H-2/H2O and CO/CO2 atmospheres. Heating introduced structural differences in the nickel layer among the pattern electrodes, which appear to affect the electrode performance. Both dense and porous nickel pattern electrodes were formed by heating. Holes appeared in the nickel
Objective Visual expertise relies on perceptive as well as cognitive processes. At present, knowledge of these processes when diagnosing clinical cases mainly stems from studies with still pictures. Patient video cases constitute a dynamic and authentic, diagnostic challenge that may simulate seeing and diagnosing a patient in person. This study investigates visual attention and the concomitant co
Background Insufficient platelet inhibition is a major determinant of stent thrombosis (STh), although the etiology is multifactorial. On-clopidogrel platelet reactivity was investigated in patients with previous angiographically confirmed STh, myocardial infarction (MI), and controls. Methods Using the Swedish Coronary Angiography and Angioplasty Registry, we identified patients with angiographic
The composition of arbuscular mycorrhizal fungi (AMF) communities found in agricultural systems has been found to be very different to that of forest. The implications of this, if any, for the restoration of indigenous forest on ex-agricultural land is poorly understood. This study investigated the effect that AMF communities isolated from ex-agricultural and forest soils have on the growth of an
Changes in Holocene coastal paleo-environment and sea-level variations have been recorded in estuary sediments from Macassa Bay, southern Mozambique. Methods include analysis of fossil diatoms, sediment stratigraphy, mineral magnetic properties, stable carbon and nitrogen isotope composition and carbon and nitrogen content. The chronology, based on six AMS C-14 dates, suggests a basal age of the s
We have previously shown that persistent a-synuclein overexpression in ventral midbrain of marmoset leads to a distinctive neurodegenerative process and motor defects. The neurodegeneration was confined to caudate putamen dopaminergic fibers in animals overexpressing wild-type (wt) alpha-synuclein. However, A53T alpha-synuclein overexpression induced neurodegeneration that resulted in nigral dopam
The effect of strong intermolecular hydrogen bonding on torsional degrees of freedom is investigated by far-infrared absorption spectroscopy for different methanol dimer isotopologues isolated in supersonic jet expansions or embedded in inert neon matrices at low temperatures. For the vacuum-isolated and Ne-embedded methanol dimer, the hydrogen bond OH librational mode of the donor subunit is fina
Upconverting nanoparticles (UCNPs) have recently shown great potential as contrast agents in biological applications. In developing different UCNPs, the characterization of their quantum yield (QY) is a crucial issue, as the typically drastic decrease in QY for low excitation power densities can either impose a severe limitation or provide an opportunity in many applications. The power density dep
Introduction: Collagen-induced arthritis (CIA) is a mouse model for rheumatoid arthritis (RA) and is induced after immunization with type II collagen (CII). CIA, like RA, is an autoimmune disease leading to destruction of cartilage and joints, and both the priming and inflammatory phases have been suggested to be dependent on proteases. In particular, the cysteine proteases have been proposed to b
To explore the potential linkage between distribution of marine bacterioplankton groups, environmental conditions, and water mass, we investigated the factors determining the abundance of bacterial taxa across the hydrographically complex Subtropical Convergence Zone in the Sargasso Sea. Based on information from 16S rRNA gene clone libraries from various locations and two depths, abundances of th
The present study investigated hierarchical lexical semantic structure in oral descriptions of concrete word meanings produced by a subject (ZZ) diagnosed with anomic aphasia due to left occipital lesions. The focus of the analysis was production of a) nouns at different levels of semantic specificity (e.g., "robin"-"bird"-"animal") and b) words describing sensory or motor experiences (e.g., "blue
Recent data suggest that platelets not only control thrombosis and hemostasis but may also regulate inflammatory processes such as acute pancreatitis. However, the specific role of platelet-derived mediators in the pathophysiology of acute pancreatitis is not known. Herein, we examined the role of CD40 ligand (CD40L, CD154) in different models of acute pancreatitis. Acute pancreatitis was induced
To study P1-P3 macrocyclizations of previously reported tertiary-alcohol-comprising HIV-1 protease inhibitors (PIs), three new 14- and 15-member macrocyclic PIs were designed, synthesized by ring-closing metathesis, and evaluated alongside with 10 novel linear PIs. Cocrystallized complexes of the macrocyclic PIs and the HIV-1 protease are presented, analyzed, and discussed. The macrocyclic structu
