Distinctive character of electronic and vibrational coherences in disordered molecular aggregates
Coherent dynamics of coupled molecules are effectively characterized by the two-dimensional electronic spectroscopy. Depending on the coupling between electronic and vibrational states, oscillating signals of purely electronic, purely vibrational or mixed character are observed with the help of oscillation maps, constructed from time-resolved spectra. Amplitude of beatings caused by electronic coh
Pharmacokinetics of budesonide and formoterol administered via 1 pressurized metered-dose inhaler in patients with asthma and COPD.
In 3 open-label studies, the systemic bioavailability of budesonide and formoterol administered via pressurized metered-dose inhaler (pMDI) or dry powder inhaler (DPI) formulations was evaluated in asthma (24 children, 55 adults) or chronic obstructive pulmonary disease (COPD; n = 26) patients. Treatments were administered at doses high enough to estimate pharmacokinetic parameters reliably. Two o
Determination of the Structures of Symmetric Protein Oligomers from NMR Chemical Shifts and Residual Dipolar Couplings
Symmetric protein dimers, trimers, and higher-order cyclic oligomers play key roles in many biological processes. However, structural studies of oligomeric systems by solution NMR can be difficult due to slow tumbling of the system and the difficulty in identifying NOE interactions across protein interfaces. Here, we present an automated method (RosettaOligomers) for determining the solution struc
Antibodies to islet cell autoantigens, rotaviruses and/or enteroviruses in cord blood and healthy mothers in relation to the 2010-2011 winter viral seasons in Israel: a pilot study
AimsTo determine whether antivirus and/or islet cell antibodies can be detected in healthy pregnant mothers without diabetes and/or their offspring at birth in two winter viral seasons. MethodsMaternal and cord blood sera from 107 healthy pregnant women were tested for islet cell autoantibodies using radioligand binding assays and for anti-rotavirus and anti-CoxB3 antibody using an enzyme-linked i
Does migratory distance affect fuelling in a medium-distance passerine migrant?: results from direct and step-wise simulated magnetic displacements.
In birds, fat accumulation before and during migration has been shown to be endogenously controlled and tuned by, among other factors, the Earth's magnetic field. However, our knowledge about the influence of the geomagnetic field on the fuelling in migrating birds is still limited to just a few nocturnally migrating passerine species. In order to study if variations of the magnetic field can also
Clinical evaluation of two consanguineous families with homozygous mutations in BEST1
Purpose: To describe the clinical and genetic findings in two consanguineous families with Best vitelliform macular dystrophy (BVMD) and homozygous mutations in the bestrophin-1 (BEST1) gene. Methods: Ophthalmologic examination was performed in eight members of two families originating from Spain and Denmark. Mutation screening was performed using the Vitelliform Macular Dystrophy mutation array f
Imaging of dynamic magnetic fields with spin-polarized neutron beams
Precession of neutron spin in a magnetic field can be used for mapping of a magnetic field distribution, as demonstrated previously for static magnetic fields at neutron beamline facilities. The fringing in the observed neutron images depends on both the magnetic field strength and the neutron energy. In this paper we demonstrate the feasibility of imaging periodic dynamic magnetic fields using a
Modeling of C IV pumped fluorescence of Fe II in symbiotic stars
Aims. We describe how the C IV lambda 1548.18 line pumps the 1548.20 and 1548.41 angstrom channels of Fe II in symbiotic stars through the process known as photo-ionization by accidental resonance (PAR). We describe where and why Fe II fluorescence arises in symbiotic stars and whether the Fe II lambda 1548.41 channel can only be activated when there is a white-dwarf wind present in the system. Fu
Variations in soil characteristics affecting the occurrence of Aphanomyces root rot of sugar beet - Risk evaluation and disease control
Damping off and chronic root rot of sugar beet caused by Aphanomyces cochlioides is a major constraint in cultivation of sugar beet, with occurrence of the disease in Sweden being concentrated to specific areas. This study examined soil factors that can be used for risk assessment of Aphanomyces root rot. Soils from 134 field plots were assessed over three years for Aphanomyces root rot potential
Reorganization Energy for Internal Electron Transfer in Multicopper Oxidases.
We have calculated the reorganization energy for the intramolecular electron transfer between the reduced type 1 copper site and the peroxy intermediate of the trinuclear cluster in the multicopper oxidase CueO. The calculations are performed at the combined quantum mechanics and molecular mechanics (QM/MM) level, based on molecular dynamics simulations with tailored potentials for the two copper
Beyond the Third Mission: Exploring the Emerging University Function of Co-creation for Sustainability
This paper explores a global trend where universities are collaborating with local government, industry and civic organisations to advance the sustainable transformation of a specific town, city or region. With empirical evidence, we argue that this function of ‘cocreation for sustainability’ could be interpreted as the seeds of an emerging, new mission for the university. We demonstrate that this
Water Signatures and Their Thermal Stability in Bedded Salt for Nuclear Waste Storage: An Incoherent Inelastic Neutron Spectroscopy Study
The forms of water and their thermal stability in bedded salt are crucial in determining the material's suitability for heat-generating nuclear waste storage. Here we show first-of-its-kind incoherent inelastic neutron scattering (IINS) results of bedded salts to distinguish three water environments: intergranular water molecules confined to grain boundaries, water trapped as brine in fluid inclus
Segmentation of Medical Images, Applications in Echocardiography and Nuclear Medicine
Segmentation is an important task in all kinds of image analysis. In medical image analysis segmentation has a great clinical value since the aim could be to localize organs or pathologies in order to raise the quality of diagnoses. This thesis consists of three papers where different segmentation techniques have been applied to different imaging modalities. In the first paper a full computer assi
Complete parameterization of temporally and spectrally resolved laser induced fluorescence data with applications in bio-photonics
We present a set of spectrally and temporally resolved clinical fluorescence data-with two separate excitation wavelengths-that was recorded in vivo. We demonstrate that data in the spectral and temporal domains are in certain ways coupled and provide a method for integrated and effective parameterization of spectrally and temporally resolved fluorescence (i.e., time-resolved emission spectra).

Relations betwee
Retigabine as add-on treatment of refractory epilepsy– a cost-utility study in a swedish setting
Abstract in Undetermined OBJECTIVES: To calculate comparative incremental cost-effectiveness ratios (cost per quality-adjusted life year, QALY) and net marginal benefits for retigabine as add-on treatment for patients with uncontrolled focal seizures as compared to add-on lacosamide treatment and no add-on treatment, respectively. MATERIALS & METHODS: Calculations were performed using a valida
Effects of soil frost on growth, composition and respiration of the soil microbial decomposer community
Most climate change scenarios predict that the variability of weather conditions will increase in coming decades. Hence, the frequency and intensity of freeze-thaw cycles in high-latitude regions are likely to increase, with concomitant effect on soil carbon biogeochemistry and associated microbial processes. To address this issue we sampled riparian soil from a Swedish boreal forest and applied t
Test-Retest Reliability of Isokinetic Knee Strength Measurements in Children Aged 8 to 10 Years.
BACKGROUND: Isokinetic dynamometry is a useful tool to objectively assess muscle strength of children and adults in athletic and rehabilitative settings. This study examined test-retest reliability of isokinetic knee strength measurements in children aged 8 to 10 years and defined limits for the minimum difference (MD) in strength that indicates a clinically important change. HYPOTHESIS: Isokine
The Tetraspanin CD9 Affords High-Purity Capture of All Murine Hematopoietic Stem Cells
Prospective isolation is critical for understanding the cellular and molecular aspects of stem cell heterogeneity. Here, we identify the cell surface antigen CD9 as a positive marker that provides a simple alternative for hematopoietic stem cell isolation at high purity. Crucially, CD9 affords the capture of all hematopoietic stem cells in murine bone marrow in the absence of contaminating populat
