Context. X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). Usually, a combination of deep and wide surveys is necessary to create a complete picture of the population. Deep X-ray surveys provide the faint population at high redshift, while wide surveys provide the rare bright sources. Nevertheless, very wide area surve
OBJECTIVE: To investigate the influence of common and low-frequency genetic variants on the risk of ischemic stroke (all IS) and etiologic stroke subtypes.METHODS: We meta-analyzed 12 individual genome-wide association studies comprising 10,307 cases and 19,326 controls imputed to the 1000 Genomes (1 KG) phase I reference panel. We selected variants showing the highest degree of association (p < 1
For most animals their foraging environment consists of a patch network. In random environments there are no spatial autocorrelation at all, while in fine-grained systems positive autocorrelations flip to negative ones and back again against distance. With increasing grain size the turnover rate of spatial autocorrelation slows down. Using a cellular automaton with foragers having limited informat
Eight children (1--17 yr) underwent bone marrow harvesting while in cytostatic-induced remission of their disease (leukemia [n = 6], Ewing sarcoma, and non-Hodgkin lymphoma). After the induction of general anesthesia, all patients were loaded with 10 mL/kg of a 6% high-molecular dextran solution (Macrodex — Pharmacia), which resulted in a significant preoperative decrease in hematocrit (Hct) from
Clinical characteristics and cytogenetic aberrations were ascertained and reviewed in a population-based consecutive series of 285 pediatric T-cell acute lymphoblastic leukemias (T-ALLs) diagnosed between 1992 and 2006 in the Nordic countries. Informative karyotypic results were obtained in 249 (87%) cases, of which 119 (48%) were cytogenetically abnormal. Most (62%) of the aberrant T-ALLs were ps
Popular Abstract in Swedish Transplantation av dopaminceller från mänskliga foster kan förbättra funktionen hos patienter med Parkinsons sjukdom (Lindvall 1997, Björklund 2000a). Man har kunnat visa att transplantaten har återställt dopaminproduktionen i striatum till normala nivåer i flera fall, och till 70-80% av normalt i majoriteten av de patienter som transplanterats i Lund. Transplantaten haTransplantation of embryonic human neural tissue can restore function in patients with Parkinson’s disease, but there is a severe shortage of donor tissue which limits the applicability of the technique. Embryonic neural tissue from other species, xenogeneic tissue, would provide a readily accessible donor tissue with the potential to help patients if the immunological reactions in the host could
Background: Potent antithrombotic therapy has significantly improved prognosis for patients with acute myocardial infarction (AMI), however, at a price of increased bleeding risk. Chronic gastric infection with Helicobacter pylori (Hp) commonly causes upper gastrointestinal bleeding and is proposed as a risk factor for subsequent bleeding post AMI. The prevalence of active Hp in a current AMI popu
Eligibility criteria for hematopoietic stem cell transplantation (HSCT) in acute lymphoblastic leukemia (ALL) vary according to disease characteristics, response to treatment, and type of available donor. As the risk profile of the patient worsens, a wider degree of HLA mismatching is considered acceptable. A total of 138 children and adolescents who underwent HSCT from HLA-identical sibling donor
Rechargeable batteries that use redox-active organic compounds are currently considered as an energy storage technology for the future. Functionalizing redox-active groups onto conducting polymers, to make conducting redox polymers (CRPs) can effectively solve the low conductivity and dissolution problems of redox-active compounds. Here we employ a solution-processible postdeposition polymerizatio
Background: Patent foramen ovale (PFO) is a contributor to embolic stroke of undetermined source (ESUS). Subgroup analyses from previous studies suggest that anticoagulation could reduce recurrent stroke compared with antiplatelet therapy. We hypothesised that anticoagulant treatment with rivaroxaban, an oral factor Xa inhibitor, would reduce the risk of recurrent ischaemic stroke compared with as
A unipolar diffusion charger with minimal particle losses in the ultrafine size range has been developed. This charger uses two radioactive α-sources to produce ions which are drawn into the charging region by an alternating electric field. The aerosol flow in the centre of the charging region is surrounded by a particle-free sheath air flow to prevent particle losses. Charged aerosol particles mo
Mutations in NPM1 can be used for minimal residual disease (MRD) analysis in acute myeloid leukemia (AML). We here applied a newly introduced method, deep sequencing, allowing for simultaneous analysis of all recurrent NPM1 insertions and thus constituting an attractive alternative to multiple PCRs for the clinical laboratory. We retrospectively used deep sequencing for measurement of MRD pre- and
Healthy adult laboratory rats were exposed to alternating negative pressure and atmospheric pressure to replicate the clinical situation found in patients with chronic sniffing habits and chronic middle ear disease. The rats were placed in a box in which the pressure changed at intervals of 30 s between atmospheric pressure and a negative pressure of -3 kPa. This was repeated continuously or perio
BACKGROUND: Comparable data on the global and country-specific burden of neurological disorders and their trends are crucial for health-care planning and resource allocation. The Global Burden of Diseases, Injuries, and Risk Factors (GBD) Study provides such information but does not routinely aggregate results that are of interest to clinicians specialising in neurological conditions. In this syst
We present a scheme for transferring conformational degrees of freedom from all-atom (AA) simulations of an intrinsically disordered protein (IDP) to coarse-grained (CG) Monte Carlo (MC) simulations using conformational swap moves. AA simulations of a single histatin 5 peptide in water were used to obtain a structural ensemble, which is reweighted in a CGMC simulation in the presence of a negative
Surrogate measures of safety (SMoS) are meant to function as tools to investigate traffic safety. The term surrogate indicates that these measures do not rely on crash data; instead, they focus on identifying safety critical events (or near-crashes) in traffic, which can be used as an alternative to crash records. The overall aim of this thesis is to explore which SMoS are suitable when analysing
Legal pluralism provided a useful alternative framework because pluralism had always sought to identify hybrid legal spaces, where multiple normative systems occupied the same social field. An emphasis on legal pluralism also freed scholars from endless intractable debates about whether international law is truly law given that coercive enforcement power in the international and transnational aren
Simultaneous label-free detection of UV absorbance and native UV-excited fluorescence in an electrophoresis microchip is presented. UV transparent integrated waveguides launch light at a wavelength of 254 nm from a mercury lamp along the length of a 1-mm long detection cell. Transmitted UV light is collected by another waveguide in the opposite end of the detection cell, while visible fluorescence
AbstractPhysical exhaustion can constrain human ascending work capacity and performance during emergency evacuation on stairs. The overall aim of this research was to explore and compare stair ascending capacities and physiological limitations during two different strategies: self-preferred pace in three different public stairways in the field, and controlled pace in a laboratory on a stair machin
