soziale Ungleichheit

description: Für die Behandlung von medizinischen Notfällen bei Menschen ohne Krankenversicherungsschutz besteht für Kliniken ein Erstattungsanspruch gegenüber Sozialleistungsträgern. Hoher Verwaltungsaufwand und rechtliche Unsicherheiten führen jedoch häufig zu hohen Behandlungskosten für die behandelnde Klinik. Neben anderen Faktoren trägt das dazu bei, dass der Zugang zur stationären Krankenhausversorgung faktisch erschwert ist. Planbare stationäre Behandlungen sind nicht möglich. Während zur Situation von Menschen ohne Krankenversicherungsschutz im ambulanten Sektor bereits einige Untersuchungen vorliegen, fehlt bislang eine breite Datenbasis zur stationären Versorgung dieses Patient:innenkollektivs.

Use of 4D Computer Tomographic Angiography to Accurately Identify Distal Internal Carotid Artery Occlusions and Pseudo-Occlusions: Technical Note
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Background and Purpose

Traditional methods of computed tomographic angiography (CTA) can be unreliable in detecting carotid artery pseudo-occlusions or in accurately locating the site of carotid artery occlusion. With these methods, lack of adequate distal runoff due to pseudo-occlusion or intracranial occlusion can result in the inaccurate diagnoses of complete occlusion or cervical carotid occlusion, respectively. The site of carotid occlusion has important therapeutic and interventional considerations. We present several cases in which 4D CTA was utilized to accurately and noninvasively diagnose carotid pseudo-occlusion and intracranial internal carotid artery (ICA) occlusion.

Methods

We identified five patients who presented to our institute with ischemic stroke symptoms and evaluated images from traditional CTA protocols and 4D CTA protocols in each of these patients, comparing diagnoses rendered by each imaging technique.

Results

In two patients, traditional CTA suggested the presence of complete ICA occlusion. However, 4D CTA demonstrated pseudo-occlusion. Similarly, in three patients, traditional CTA demonstrated cervical ICA occlusion, whereas the 4D CTA demonstrated intracranial ICA occlusion
Revisiting strong coupling QCD at finite temperature and baryon density

description: The strong coupling limit ($β_{gauge}=0$) of lattice QCD with staggered fermions enjoys the same non-perturbative properties as continuum QCD, namely confinement and chiral symmetry breaking. In contrast to the situation at weak coupling, the sign problem which appears at finite density can be brought under control for a determination of the full (mu,T) phase diagram by Monte Carlo simulations. Further difficulties with efficiency and ergodicity of the simulations, especially at the strongly first-order, low-T, finite-mu transition, are addressed respectively with a worm algorithm and multicanonical sampling. Our simulations reveal sizeable corrections to the old results of Karsch and Muetter. Comparison with analytic mean-field determinations of the phase diagram shows discrepancies of O(10) in the location of the QCD critical point.

description: We study the entropy of extremal warped black hole obtained from the topologically massive gravity with a negative cosmological constant of $Λ=-1/l^2$. We compare the entropy $S_e=πα/3G$ from the Wald formalism with $S_w=πl u /3G$ from the entropy function approach. These are the same if $α=l u$. Also we obtain the same Cardy formula when $J_e= l^3 q$ with $J_e$ the angular momentum and $q$ the conserved quantity.

description: For each clone C on a set A there is an associated equivalence relation analogous to Green's R-relation, which relates two operations on A if and only if each one is a substitution instance of the other using operations from C. We study the maximal and submaximal clones on a three-element set and determine which of them have only finitely many relative R-classes.

description: We review Darboux-Crum transformation of Heun's differential equation. By rewriting an integral transformation of Heun's differential equation into a form of elliptic functions, we see that the integral representation is a generalization of Darboux-Crum transformation. We also consider conservation of monodromy with respect to the transformations.

description: Lactoferin (Lf) is an iron-binding glycoprotein belonging to the transferrin family and it is present at high levels in breast milk and colostrum. This protein has many known functions and it is a potential antibacterial, antiviral, immunostimulatory, antioxidant, and cancer preventive agent.It has been seen that a 105 kDa Lf receptor (LfR) specifically mediates the effects of Lf in several different cell types (1). In human cholangiopathies, cholangiocytes are able to proliferate and replace the cell loss restoring the integrity of damaged biliary epithelium. However, when cholangiocyte proliferation is severely impaired, the activation of facultative hepatic progenitor cells (HPCs) takes place (2). The aims of our study have been i) to investigate the expression of Lf and LfR in cholangiocytes and in HPCs both in rats and in humans; and ii) to evaluate the in vitro effects of bLf on cholangiocyte proliferation and on HPC activation. Liver specimens have been obtained from normal (N=5) and bile duct ligated (BDL) (N=5) rats; from normal patients (N=5) and from patients with primary biliary cirrhosis (PBC, N=5); Specimens were processed for histology, immunohistochemistry and immunofluorescence. Moreover for the in vitro study small and large cholangioytes from mouse, human non malignant cholangiocytes (H69), and HPCs treated or not with lactoferrin were used. Our results showed that: i) cholangiocytes and hepatic progenitor cells express lactoferrin and its receptor, ii) cholangiocytes and HPC proliferation is enhanced by lactoferrin; iii) the treatment with lactoferrin determine the commitment of HPCs towards cholangiocyte fate; this commitment is characterized by HPC morphological and phenotypical changes. Our current findings suggest that modulation of lactoferrin may be an important therapeutic tool for managing the proliferation of cholangiocyte and the activation of progenitor cell compartment in biliary disorders.

description: The problem of nonuniqueness of minimal coupling procedure for Einstein--Cartan (EC) gravity with matter is investigated. It is shown that the predictions of the theory of gravity with fermionic matter can radically change if the freedom of addition of a divergence to the flat space matter Lagrangean density is exploited. The well--known gravity induced four--fermion interaction is shown to reveal unexpected features. The solution to the problem of nonuniqueness of minimal coupling of EC gravity is argued to be necessary in order for the theory to produce definite predictions. In particular, the EC theory with fermions is shown to be indistinguishable from usual General Relativity on the effective level, if the flat space fermionic Lagrangean is appropriately chosen. Hence, the solution to the problem of nonuniqueness of minimal coupling procedure is argued to be necessary if EC theory is to be experimentally verifiable. It could also enable experimental tests of theories based on EC, such as loop approach to quantisation of gravitational field. Some ideas of how the arbitrariness incorporated in EC theory could be restricted or even eliminated are presented.

description: Dendritic cells (DCs) induce, sustain, and regulate immune responses and are essential mediators of immunity and tolerance. These cells are specialized to capture antigens, process and present them to T cells to initiate immune responses towards pathogens and tumours. DCs are heterogeneous for origin, anatomical localization, phenotype and function. They differentiate from haematopoietic stem cells-derived precursors, migrate from sites of antigen uptake to lymphoid organs, mature and interact with lymphocytes. Langerhans cells (LCs) are immature DCs, are located in stratified squamous epithelia of the epidermis and mucosae. LCs express CD1a, langerin/ CD207, E-cadherin and have intracytoplasmic Birbeck granules. We wonder if the PPAR (peroxisome proliferator activated receptor)-gamma stimulation can give rise to LCs in vitro starting from CD14+ monocytes, as occurs with CD133+ haematopoietic precursors (1). Circulating CD14+ monocytes have been isolated by immunomagnetic separation and cultured with GM-CSF, IL-4, TNF-α and TGF-β for 7 days. The complete maturation was induced by further culture for 48 h with the same cytokines, but the concentration of the TGF-β was increased (2). Rosiglitazone was used to stimulate PPAR-γ from the start of the culture. The cells were analysed by phase contrast, electron microscopy, immunofluorescence, flow cytometry and mixed lymphocyte reaction. All cultures generated mature cells that expressed MHCII intensely, both with and without rosiglitazone, and had lymphocyte stimulating activity. The obtained DCs express the DC-SIGN, such as connective tissue DCs, more intensely with than without rosiglitazone. Some of these cells were CD1a+ and among them a small part was CD207+, i.e. they were LC-like, however they never contained Birbeck granules. The percentages of cells CD1a+ and CD207+ were slightly higher without rosiglitazone. The results indicate that upon addition of rosiglitazone the in vitro differentiation of monocytes to LCs is hampered, at variance with what happens with cultures of CD133+ precursors. For this reason, experiments have been planned with CD34+ haematopoietic stem cells, because the generation of different types of DCs is a necessary step to gain control on these cells for medical purposes.

description: The paper contains a simplified and improved version of the results obtained by the authors earlier. Wave propagation is discussed in a network of branched thin wave guides when the thickness vanishes and the wave guides shrink to a one dimensional graph. It is shown that asymptotically one can describe the propagating waves, the spectrum and the resolvent in terms of solutions of ordinary differential equations on the limiting graph. The vertices of the graph correspond to junctions of the wave guides. In order to determine the solutions of the ODE on the graph uniquely, one needs to know the gluing conditions (GC) on the vertices of the graph. Unlike other publications on this topic, we consider the situation when the spectral parameter is greater than the threshold, i.e., the propagation of waves is possible in cylindrical parts of the network. We show that the GC in this case can be expressed in terms of the scattering matrices related to individual junctions. The results are extended to the values of the spectral parameter below the threshold and around it.

description: The article presents the following research results of new approaches in the optimization of the phase structure of the field crawl stroke: correction of the trajectory of the hand movement in the initial phases of the stroke provides an effective grip to create propulsive forces in the subsequent phases of the stroke; increasing the variability and efficiency of swimming technique due to the optimally built structure of the swimming cycle creates technical and tactical advantage for the swimmers allowing for effective completion of the final parts of front crawl distances. The results can be used in sports schools, swimming centers and other organizations involved in the training of high-skilled swimmers, as well as in high schools and courses of professional development and advanced training of specialists in swimming.

On the behaviour of the solutions of certain Schredinger equations for vanishing potentials
Creators: name: Rome, Tovie Leon
Publisher: name: University of British Columbia
Year: 2012

description: In studying the diamagnetism of free electrons in a uniform magnetic field it was found that reducing the field to zero in the wavefunction did not yield the experimentally indicated free particle plane wave wavefunction. However, solving the Schroedinger Equation resulting from setting the field equal to zero in the original equation did yield a plane wave wavefunction. This paradox was not found to be peculiar to the case of a charged particle in a uniform magnetic field but was found to occur in a number of other systems. In order to gain an understanding of this unexpected behavior, the following systems were analyzed: the one-dimensional square well potential; a charged, spinless particle in a Coulomb field and in a uniform electric field; a one-dimensional harmonic oscillator; and a charged, spinless particle in a uniform magnetic field. From these studies the following were obtained: conditions for determining the result of reducing the potential in a wavefunction; the condition under which the potential of a system may be switched off while maintaining the energy of the system constant; the relationship between the result of physically switching off a potential, the result of reducing it in the wavefunction, and the solution of the Schroedinger Equation obtained by decreasing the potential to zero in the original wave equation; and a general property of any wavefunction with respect to reducing any parameter within this wavefunction.

description: The interest for lipid metabolism in the stem cell field has increased in the last few years (1,2,3). Membrane lipidomics embraces many aspects of cell metabolism and the role of lipids is now considered more than merely inert and structural in delimitating the extra- and intra-cellular compartments (4,5). Nevertheless, we are still far from understanding the impact of membrane lipidomics in stemness maintenance and differentiation patterns. The aim of our work was to study membrane lipidomics of mesenchymal stromal cells derived from human placenta and correlate it to specific biological properties, by using chemically- defined tailored lipid supplements (Refeed®). In the experimental study, the cell membranes of freshly isolated mesenchymal stromal cells obtained from human fetal membranes (FM-MSCs) were characterized for fatty acid composition. Then, we investigated cell morphology, viability, proliferation, differentiation and immunomodulation after in-vitro exposure to Refeed® supplements. Control MSCs were cultured without lipid supplementation. Our results showed a significant reduction of membrane fluidity for in-vitro primary cells, with cell membrane fatty acid composition greatly differing from the in-vivo one. By tailoring lipid supplementation, the fatty acid composition and biophysical properties of in-vitro cell membranes resulted more similar to the in-vivo counterparts, with higher omega-6 fatty acid content and increased membrane fluidity. These modifications of membrane composition and properties had no effect on cell morphology and viability, whereas ameliorated cell proliferation rate, diffentiation ability and immunomodulatory properties. In particular, supplemented FMMSCs showed an increased expression of cell membrane molecules like Vascular Endothelial Growth Factor Receptors 1 (VEGFR-1 or Flt-1) and 2 (VEGFR-2 or KDR), that correlated with a more efficient response to angiogenic commitment. Moreover, regarding immunomodulation, supplemented FM-MSCs displayed an increased expression of the tolerogenic cell surface protein HLA-G, that positively influenced the in-vitro cell immunomodulatory ability. Finally, these data suggest that specific lipid supplementation have functional consequences on in-vitro MSC behavior and may influence cell-based therapeutic approaches.

description: Hydrogels have attracted considerable attention in biomedical engineering applications due to their many favorable biomimetic properties. Hydrogels based on proteins or carbohydrates can also function as effective extracellular matrices to direct cellular behavior. Recently, polysaccharide based hydrogels have become particularly interesting as matrices for the repair and regeneration of a wide variety of tissues and organs. The incorporation of inorganic minerals as hydroxyapatite nanoparticles can modulate the performance of the hydrogel with potential applications for bone tissue engineering. The aim of this study was to verify the biological potential of a new carboxymethyl cellulose—hydroxyapatite hybrid hydrogel in bone tissue regeneration. Mesenchymal stem cells were seeded on hydrogel scaffold, in presence and absence of hydroxyapatite, for 7, 14 and 21 days. Cell viability assay and morphological analysis were carried out to evaluate biocompatibility and cell adhesion of the materials. Real Time PCR for genes involved in tissue regeneration was carried out to assay the influence of the scaffold in cell differentiation. Results showed a high cell viability and biocompatibility of the tested material, confirmed by morphological analysis. The evaluation of osteoblast markers demonstrated the osteogenic induction of the 3D material enriched with hydroxyapatite in the production of mineralized extracellular matrix compared to the carboxymethyl cellulose based material. In conclusion, our data show that carboxymethyl cellulose—hydroxyapatite hybrid hydrogel may have great potential in bone tissue engineering applications.

description: Since 1997, BL Lacertae has undergone a phase of high optical activity, with the occurrence of several prominent outbursts. Starting from 1999, the Whole Earth Blazar Telescope (WEBT) consortium has organized various multifrequency campaigns on this blazar, collecting tens of thousands of data points. One of the main issues in the study of this huge dataset has been the search for correlations between the optical and radio flux variations, and for possible periodicities in the light curves. The analysis of the data assembled during the first four campaigns (comprising also archival data to cover the period 1968-2003) revealed a fair optical-radio correlation in 1994-2003, with a delay of the hard radio events of ~100 days. Moreover, various statistical methods suggested the existence of a radio periodicity of ~8 years. In 2004 the WEBT started a new campaign to extend the dataset to the most recent observing seasons, in order to possibly confirm and better understand the previous results. In this campaign we have collected and assembled about 11000 new optical observations from twenty telescopes, plus near-IR and radio data at various frequencies. Here, we perform a correlation analysis on the long-term R-band and radio light curves. In general, we confirm the ~100-day delay of the hard radio events with respect to the optical ones, even if longer (~200-300 days) time lags are also found in particular periods. The radio quasi-periodicity is confirmed too, but the "period" seems to progressively lengthen from 7.4 to 9.3 years in the last three cycles. The optical and radio behaviour in the last forty years suggests a scenario where geometric effects play a major role. In particular, the alternation of enhanced and suppressed optical activity (accompanied by hard and soft radio events, respectively) can

Space-Dependent Step Features: Transient Breakdown of Slow-roll, Homogeneity and Isotropy During Inflation

description: A step feature in the inflaton potential can model a transient breakdown of slow-roll inflation. Here we generalize the step feature to include space-dependence, allowing it also to model a breakdown of homogeneity and isotropy. The space-dependent inflaton potential generates a classical curvature perturbation mode characterized by the wavenumber of the step inhomogeneity. For inhomogeneities small compared with the horizon at the step, space-dependence has a small effect on the curvature perturbation. Therefore the smoothly oscillating quantum power spectrum predicted by the homogeneous step is robust with respect to sub-horizon space-dependence. For inhomogeneities equal to or greater than the horizon at the step, the space-dependent classical mode can dominate, producing a curvature perturbation in which modes of wavenumber determined by the step inhomogeneity are superimposed on the oscillating power spectrum. Generation of a space-dependent step feature may therefore provide a mechanism to introduce primordial anisotropy into the curvature perturbation. Space-dependence also modifies the quantum fluctuations, in particular via resonance-like features coming from mode coupling to amplified superhorizon modes. However these effects are small relative to the classical modes.

The influence of the C+N+O abundances on the determination of the relative ages of Globular Clusters: the case of NGC 1851 and NGC 6121 (M4)

description: The color magnitude diagram (CMD) of NGC 1851 presents two subgiant branches (SGB), probably due the presence of two populations differing in total CNO content. We test the idea that a difference in total CNO may simulate an age difference when comparing the CMD of clusters to derive relative ages. We compare NGC 1851 with NGC 6121 (M4), a cluster of very similar [Fe/H]. We find that, with a suitable shift of the CMDs that brings the two red horizontal branches at the same magnitude level, the unevolved main sequence and red giant branch match, but the SGB of NGC 6121 and its red giant branch "bump" are fainter than in NGC 1851. In particular, the SGB of NGC 6121 is even slightly fainter than the the faint SGB in NGC 1851. Both these features can be explained if the total CNO in NGC 6121 is larger than that in NGC 1851, even if the two clusters are coeval. We conclude by warning that different initial C+N+O abundances between two clusters, otherwise similar in metallicity and age, may lead to differences in the turnoff morphology that can be easily attributed to an age difference.

A transistorized decoder for pulse code modulation
Creators: name: Chang, Juang-Chi
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is concerned with the construction of a transistorized pulse code modulation decoder, the purpose of which is to decode the digital signal into the continuous analog form. The earlier part of this thesis describes the design and construction of a transistorized decoder using the circulated pulse principle. This turned out to be not too practical. The latter part concerns the design and construction of a PCM decoder using a ferrite-core shift register. This design was successful. The decoder has been tested in conjunction with the coder built by R.A. Hafer.
