The high-spectral-resolution optical studies of the energy gap evolution, supplemented with electronic, magnetic, and structural characterization, show that the modification of the GaAs valence band caused by Mn incorporation occurs already for a very low Mn content, much lower than that required to support ferromagnetic spin-spin coupling in (Ga,Mn)As. Only for n-type (Ga,Mn)As with the Mn conten

Working within the Langevin framework of nuclear shape dynamics, we study the dependence of the evolution on the degree of excitation. As the excitation energy of the fissioning system is increased, the pairing correlations and the shell effects diminish and the effective potential-energy surface becomes ever more liquid-drop like. This feature can be included in the treatment in a formally well-f

The aim was to explore magnetic resonance imaging (MRI) experiences of patients with spinal metastasis after adjustments to the examination procedures have been made in accordance with the findings from a previous study. MRI is an important medical technology, which is considered to be the first choice of examination method when diagnosing and evaluating spinal metastatic tumors. It is a challenge

Bakgrund till projektet kring Winstrups mumie tog sin början i och med det beslut som fattades av Länsstyrelsen 2012-03-21 (Dnr 433-1675-12) som svar på en ansökan av Lunds domkyrkoförsamling om flytt av Peder Winstrups kista till Domkyrkomuseet i Lund. I denna rapport redovisas, förutom bakgrunden och resultatet, följande bilagor:Bilaga 1: Vetenskapliga undersökningar av Peder Winstrups mumie av

The azimuthal anisotropy coefficient v2 of prompt D0, D+, D∗+, and Ds+ mesons was measured in midcentral (30%-50% centrality class) Pb-Pb collisions at a center-of-mass energy per nucleon pair sNN=5.02 TeV, with the ALICE detector at the LHC. The D mesons were reconstructed via their hadronic decays at midrapidity, |y|

Iron deficiency without anemia and iron deficiency anemia are common and frequently overlooked complications of inflammatory bowel disease. Despite the frequency and impact of iron deficiency in inflammatory bowel disease, there are gaps in our understanding about its incidence, prevalence and natural history and, consequently, patients may be undertreated. Medical registries have a key role in co

A common European Community driving licence was established in 1980. However, there are major differences among the countries as regards medical conditions that legally affect driving ability. This article discusses various assessment guidelines for dizzy patients. These range from a total absence of specified binding requirements in Finland or regulations open to clinical interpretation in Switze

The three-dimensional structure of a 42-residue fragment containing the N-terminal EGF-like module of blood coagulation factor X was determined by means of 2D NMR spectroscopy and computer simulation. The spectroscopic data consisted of 370 NOE distances and 27 dihedral angle constraints. These were used to generate peptide conformations by molecular dynamics simulation. The simulations used a nov

Objectives: At a European Society of Neuroradiology (ESNR) Annual Meeting 2015 workshop, commonalities in practice, current controversies and technical hurdles in glioma MRI were discussed. We aimed to formulate guidance on MRI of glioma and determine its feasibility, by seeking information on glioma imaging practices from the European Neuroradiology community. Methods: Invitations to a structured

Domains homologous to the epidermal growth factor (EGF) are important building blocks for extracellular proteins. Proteins containing these domains have been shown to function in such diverse biological processes as blood coagulation, complement activation, and the developmental determination of embryonic cell fates. Many of these proteins require calcium for their biological function. In the case

Background: Axillary lymph node status is one of the most important prognostic factors for breast cancer. The aim of this study was to determine predictive factors for metastasis to sentinel node (SN) in primary invasive breast cancer. Method: This is a study of 3979 patients with primary breast cancer during 2008-2013 in Malmö and Lund scheduled for surgery and included in the information retriev

The complete 1H NMR assignments have been obtained for five mutant proteins of calbindin D9k and the three-dimensional solution structures determined for two of the mutants. The structures have been determined using distance geometry and simulated annealing, with distance constraints from NMR. All mutants have modifications in the first calcium-binding site of calbindin (the N-terminal site design

A simplified description and a corresponding force field for polypeptides is introduced. Each amino acid residue is reduced to one interaction site, representing the backbone, and one or two side chain sites depending on its size and complexity. Site–site interactions are parameterized after a hydrophobicity criterium. The treatment of backbone sites is in addition designed to reproduce typical po

Background: Fetal cardiovascular magnetic resonance (CMR) imaging may provide a valuable adjunct to fetal echocardiography in the evaluation of congenital cardiovascular pathologies. However, dynamic fetal CMR is difficult due to the lack of direct in-utero cardiac gating. The aim of this study was to investigate the effectiveness of a newly developed Doppler ultrasound (DUS) device in humans for

Background: Western multicenter studies on distal pancreatectomy with celiac axis resection (DP-CAR), also known as the Appleby procedure, for locally advanced pancreatic cancer are lacking. We aimed to study overall survival, morbidity, mortality and the impact of preoperative hepatic artery embolization (PHAE). Methods: Retrospective cohort study within the European-African Hepato-Pancreato-Bili

Monte Carlo simulations of linear polyelectrolytes together with explicit ions have been performed in a spherical cell model to study conformational changes and activity coefficients in relation to the isoionic dilution method used in viscosity measurements. The results show that it is possible to define an effective ionic strength that will keep the average chain conformation constant on isoionic

The isoionic dilution method was used to measure the intrinsic viscosity, [η], and the Huggins coefficient, K(H), of two poly(acrylic acid) samples, 50% neutralized with NaOH, with molecular weights 5.0 x 103 (Na50PA5) and 4.8 x 104 (Na50PA48) at different ionic strengths. For Na50PA5 at low ionic strength, [η] is higher than the value predicted by a rigid-rod model. Assuming that the chain has re

Trait-associated loci often map to genomic regions encoding long noncoding RNAs (lncRNAs), but the role of these lncRNAs in disease etiology is largely unexplored. We show that a pair of sense/antisense lncRNA (6p22lncRNAs) encoded by CASC15 and NBAT1 located at the neuroblastoma (NB) risk-associated 6p22.3 locus are tumor suppressors and show reduced expression in high-risk NBs.
