Influence of Antiphospholipid Antibody-Associated Thrombophilia on the Risk of Preterm Birth: A Systematic Review
Creators: name: Bratosin, Felix
Publisher: name: Open Science Framework
Year: 2023
Subjects: subject: Medicine and Health Sciences

description: The primary hypothesis of this study is that aPL-associated thrombophilia significantly increases the risk of preterm birth. We hypothesize that this risk may be modulated by several factors, such as the specific type of aPL present, the patient's history of thrombotic events, and co-existing autoimmune disorders. Additionally, it was assumed that the effect of aPL-associated thrombophilia on preterm birth may be mediated by complications such as preeclampsia and intrauterine growth restriction. By addressing these re-search questions, this systematic review aims to improve our understanding of APS's impact on preterm birth, providing valuable insights for clinicians and researchers alike. Therefore, we have conducted a systematic review focusing on the influence of aPL-associated thrombophilia on the risk of preterm birth, aiming to quantify the risk of preterm birth associated with aPL-associated thrombophilia. Secondly, we plan to elucidate the effect of various clinical and demographic factors on this risk. Lastly, we hope to identify gaps in the current knowledge base, thus providing direction for future research.

description: Macroscopic, phenomenological models are useful as concise framings of our understandings in fields from statistical physics to finance to biology. Constructing a phenomenological model for development would provide a framework for understanding the complicated, regulatory nature of oogenesis and embryogenesis. Here, we use a data-driven approach to infer quantitative, precise models of human oocyte maturation and pre-implantation embryo development, by analysing clinical In-Vitro Fertilization (IVF) data on 7399 IVF cycles resulting in 57 827 embryos. Surprisingly, we find that both oocyte maturation and early embryo development are quantitatively described by simple models with minimal interactions. This simplicity suggests that oogenesis and embryogenesis are composed of modular processes that are relatively siloed from one another. In particular, our analysis provides strong evidence that (i) pre-antral follicles produce anti-Müllerian hormone independently of effects from other follicles, (ii) oocytes mature to metaphase-II independently of the woman’s age, her BMI and other factors, (iii) early embryo development is memoryless for the variables assessed here, in that the probability of an embryo transitioning from its current developmental stage to the next is independent of its previous stage. Our results both provide insight into the fundamentals of oogenesis and embryogenesis and have implications for the clinical IVF.

description: The observation of a two dimensional electron gas (2DEG) (1, 2), superconductivity (3, 4), magnetic effects (5) and electronic phase separation (6-8) at the interfaces of insulating oxides, especially LaAlO3/SrTiO3, has further enhanced the potential of complex oxides for novel electronics. The occurrence of the 2DEG is strongly believed to be driven by the polarization discontinuity (9) at the interface between the two oxides. In this scenario, the crystal orientation plays an important role and no conductivity would be expected for e.g., the interface between LaAlO3 and (110)-oriented SrTiO3, which should not have a polarization discontinuity (10, 11). Here, we report the observation of unexpected conductivity at the LaAlO3/SrTiO3 interface prepared on (110)-oriented SrTiO3. The conductivity was further found to be strongly anisotropic, with the ratio of the conductance along the different directions parallel to the substrate surface showing a remarkable dependence on the oxygen pressure during deposition. The conductance and its anisotropy are discussed based on the atomic structure at the interface, as revealed by Scanning Transmission Electron Microscopy (STEM) and further supported by density functional theory (DFT) calculations.

description: Improving students academic performance is not an easy task for the academic community of higher learning. The academic performance of engineering and science students during their first year at university is a turning point in their educational path and usually encroaches on their General Point Average,GPA in a decisive manner. The students evaluation factors like class quizzes mid and final exam assignment lab work are studied. It is recommended that all these correlated information should be conveyed to the class teacher before the conduction of final exam. This study will help the teachers to reduce the drop out ratio to a significant level and improve the performance of students. In this paper, we present a hybrid procedure based on Decision Tree of Data mining method and Data Clustering that enables academicians to predict students GPA and based on that instructor can take necessary step to improve student academic performance.

description: With this paper our objective is to study the effects of different deficit policies in an endogenous growth model with publicly funded human capital accumulation and public debt, where we allow for heterogeneous households. Two types of households are considered. One household acquires human capital or skills through education while the other household remains low-skilled. Aggregate production is given by a function with physical capital and labor as input factors, where total labor input is modeled by a CES function with high-skilled and low-skilled labor as arguments. The government can run into debt, but, the primary surplus is a positive function of public debt which guarantees that public debt is sustainable. We study the characteristics and stability of the steady state and we investigate the effects of fiscal policy with regard to long-run growth and the distribution of welfare of the two households. Further, we analyze growth and welfare effects of switching from a balanced government budget to permanent public deficits taking into account transition dynamics.

description: This report summarises information regarding groundwater processes considered to have direct influence on the water balance for the Great Artesian Basin (GAB). These processes are recharge, discharge, and connectivity within the GAB sequence, as well as connectivity with underlying basins and overlying cover. The substantial body of literature available on the GAB gives the impression that there is a considerable degree of understanding of the GAB groundwater system. This is, however, misleading. The reality is that many reports and reviews have been cited or reworked from pre-existing studies without carrying over the original uncertainties. Over time, the scale of knowledge gaps has been reduced only incrementally, while there has been a growing appreciation of the complexities in the system. With so much conceptual and quantitative uncertainty, much additional investigation is still required.

description: The revision of an hip prosthesis can have different reasons. One frequent cause, especialley after implantation of a conventional cup, is the so called stress-shielding effect which can lead to a migration or loosening. Patientspecific hip cups can be used to counteract this. However, individual hip cups are only implanted for the treatment of great deformations or tumours because of the cost-intensive manufacturing. Within this project a patient-specific hip cup prosthesis has to be developed and manufactured. Besides the numerical design by means of a coupling between multi-body simulation (MBS) and finite element method (FEM), an inovative concept for the production of patientindividual hip prosthesis out of titanium sheets is introduced in this study.

description: In case of loss of the auditory ossicular chain, the application of a middle ear prosthesis is necessary. For this prosthesis, a silicone pad shall be developed to minimize pressure peaks and for the prevention of forcing of the tympanic membrane. It is important to adjust the mechanical properties for best hearing quality. Therefore different siloxanes and additives like nanoporous silica nanoparticles are used. The latter also can act as drug carriers. The visco-elastic properties of the silicone can be changed significantly by slight variations of the composition.
From Kemet to the New World: History and Reception of the first Egyptian Collection in Latin America

Year: 2018

description: This paper aims to analyse the process of formation of the Egyptian collection of the Royal/Imperial Museum (currently National Museum of Federal University of Rio de Janeiro – State of Rio de Janeiro, Brazil), situating it in the nineteenth-century contexts of collecting of curiosities and formation of museums, and relating it to the diverse modalities of collection of Egyptian antiquities present in Imperial Brazil. This collection, acquired in 1826, is extremely important for an understanding of the collecting practices of the period and their relationship to the establishment of interest in ancient Egypt in the New World. This collection of Egyptian antiquities reinforced the original mission of the Museum, that of mirroring itself in the great European museums, as well as following the collecting tendencies of these nations. In addition, the collection gained remarkable prominence in its time, and it is possible to retrace the trajectory of the uses given to it by the institution as a way to understand its many forms of reception and meaning during the nineteenth century.
Tragically on 2 September 2018 the Egyptian collection of the National Museum of UFRJ was largely destroyed in a fire, which devastated the entire museum. It is probable that stone objects have survived, but the majority of this seven-hundred-item collection, including the mummies and their coffins, no longer exists.

description: In the inverse seesaw mechanism where the spontaneously broken B-L symmetry induces tiny B-L violating Majorana masses for right-handed neutrinos, non-standard Higgs signatures can arise due to a possible Higgs doublet and singlet mixing and/or Higgs boson decays to a left- and right-handed neutrino. This leads to a remarkable feature of hadronically quiet di-lepton final states which can exhibit, in particular, lepton flavour violating signatures coming from flavour-dependent neutrino Yukawa couplings. In this process, one lepton coming from the right-handed decay could be soft enough can be missed by the trigger level cuts of CMS and ATLAS for the di-lepton plus missing energy signature. The prospects of such a signature are investigated for 8 TeV and 14 TeV center of mass energy of the LHC, taking the maximum value of the allowed neutrino Yukawa coupling and the right-handed neutrino mass of 100 GeV. A PYTHIA level simulation shows that the integrated luminosity of 10--20/fb and 1.6/fb for 8 TeV is required to observe the inclusive leptonic and lepton flavour violating signatures, respectively. For 14 TeV, the reach is more and a larger parameter space of the inverse seesaw model can be probed.

description: To optimize the function of implants the formation of surrounding connective tissue should be adapted in dependence to the mechanical conditions. Therefore, with nanostructured silica coated Bioverit® II implants were only partly reacted with recombinant BMP-2. The histology was compared 28, 84 and 301 days after implantation in the rabbit middle ear and subcutis, respectively. The whole tissue blocks were embedded in Epon, sequentially grinded, stained with Toluidine Blue O and Eosin G. The granulation tissue covering the implants varies related to cell types, cell amounts, extracellular matrix and vessels. Whereas the high cell density and the angiogenesis predominated in the subcutis, the formation of new bone could only be recognized in the scar around the implants in the middle ear.

description: We report electrical characterization of monolayer molybdenum disulfide (MoS2) devices using a thin layer of polymer electrolyte consisting of poly(ethylene oxide) (PEO) and lithium perchlorate (LiClO4) as both a contact-barrier reducer and channel mobility booster. We find that bare MoS2 devices (without polymer electrolyte) fabricated on Si/SiO2 have low channel mobility and large contact resistance, both of which severely limit the field-effect mobility of the devices. A thin layer of PEO/ LiClO4 deposited on top of the devices not only substantially reduces the contact resistance but also boost the channel mobility, leading up to three-orders-of-magnitude enhancement of the field-effect mobility of the device. When the polymer electrolyte is used as a gate medium, the MoS2 field-effect transistors exhibit excellent device characteristics such as a near ideal subthreshold swing and an on/off ratio of 106 as a result of the strong gate-channel coupling.

description: The cosmic microwave background (CMB) provides us with our most direct observational window to the early universe. Observations of the temperature and polarization anisotropies in the CMB have played a critical role in defining the now-standard cosmological model. In this contribution we review some of the basics of CMB science, highlighting the role of observations made with ground-based and balloon-borne Antarctic telescopes. Most of the ingredients of the standard cosmological model are poorly understood in terms of fundamental physics. We discuss how current and future CMB observations can address some of these issues, focusing on two directly relevant for Antarctic programmes: searching for gravitational waves from inflation via B-mode polarization, and mapping dark matter through CMB lensing.

description: The availaible data on the D0 to K0S pi+ pi- decays are analysed in the framework of the quasi two-body QCD factorization approximation. The annihilation, via W-exchange, amplitudes are added to the weak-decay tree amplitudes. The doubly Cabibbo suppressed parts of the amplitudes are also considered. The strong interactions between the kaon-pion and pion-pion pairs in the S-, P- and D-final states are described in terms of the corresponding form factors. The kaon-pion or pion-pion scalar and vector form factors are constrained by other experimental data. Unitarity, analyticity and chiral symmetry are also used to obtain their functional forms. We go through a minimization procedure to reproduce the K0S pi-, K0S pi+ and pi+ pi- effective mass projections of the Dalitz plot distributions. The large number (27) of non-zero amplitudes leads to a large number of parameters. The resulting model distributions and branching fractions are compared to the accurate Belle Collaboration data.

description: We present the results of a search for high-energy gamma-ray emission from a large sample of galaxy clusters sharing the properties of three existing Fermi-LAT detections (in Perseus, Virgo and Abell 3392), namely a powerful radio source within their brightest cluster galaxy (BCG). From a parent, X-ray flux-limited sample of clusters, we select 114 systems with a core-dominated BCG radio flux above 50 or 75 mJy, stacking data from the first 45 months of the Fermi mission, to determine statistical limits on the gamma-ray fluxes of the ensemble of candidate sources. For a >300 MeV selection, the distribution of detection significance across the sample is consistent with that across control samples for significances <3 sigma, but has a tail extending to higher values, including three >4 sigma signals which are not associated with previously identified gamma-ray emission. Modelling of the data in these fields results in the detection of four non-2FGL Fermi sources, though none appear to be unambiguously associated with the BCG candidate. A search at energies >3 GeV hints at emission from the BCG in A 2055, which hosts a BL Lac object. There is no evidence for a signal in the stacked data, and the upper limit derived on the gamma-ray flux of an average radio-bright BCG in the sample is an order-of-magnitude more constraining than that calculated for individual objects. F(1 GeV)/F(1.4 GHz) <15, compared with ~120 for NGC 1275 in Perseus, which might indicate a special case for those objects detected at high energies; that beamed emission from member galaxies comprise the dominant bright gamma-ray sources in clusters.

description: Hydrogels are a versatile tool for a multitude of applications in biomedical research and clinical practice. Especially collagen and fibrin hydrogels are distinguished by their excellent biocompatibility, natural capacity for cell adhesion and low immunogenicity. In many ways, collagen and fibrin represent an ideal biomaterial, as they can serve as a scaffold for tissue regeneration and promote the migration of cells, as well as the ingrowth of tissues. On the other hand, pure collagen and fibrin materials are marked by poor mechanical properties and rapid degradation, which limits their use in practice. This paper will review methods of modification of natural collagen and fibrin materials to next-generation materials with enhanced stability. A special focus is placed on biomedical products from fibrin and collagen already on the market. In addition, recent research on the in vivo applications of collagen and fibrin-based materials will be showcased. © 2016 by De Gruyter.

description: The zero energy modes induced by vacancies in ABC stacked trilayer graphene are investigated. Depending on the position of the vacancy, a new zero energy solution is realised, different from those obtained in multilayer compounds with Bernal stacking. The electronic modification induced in the sample by the new vacancy states is characterised by computing the local density of states and their localisation properties are studied by the inverse participation ratio. We also analyse the situation in the presence of a gap in the spectrum due to a perpendicular electric field.

description: The photo-production of $J/Ψ$-$^3He$ bound state ($[^3He]_{J/Ψ}$) on a $^4He$ target has been investigated using the impulse approximation. The calculations have been performed using several $γ+N \rightarrow J/Ψ+N$ models based on the Pomeron-exchange and accounting for the pion-exchange mechanism at low energies. The $J/Ψ$ wavefunctions in $[^3He]_{J/Ψ}$ are generated from various $J/Ψ$-nucleus potentials which are constructed by either using a procedure based on the Pomeron-quark coupling mechanism or folding a $J/Ψ$-N potential ($v_{J/Ψ,N}$) into the nuclear densities. We consider $v_{J/Ψ,N}$ derived from the effective field theory approach, Lattice QCD, and Pomeron-quark coupling mechanism. The upper bound of the predicted total cross sections is about $0.1 - 0.3$ pico-barn. We also consider the possibility of photo-production of a six quark-$J/Ψ$ bound state ($[q^6]_{J/Ψ})$ on the $^3He$ target. The Compound Bag Model of $NN$ scattering and the quark cluster model of nuclei are used to estimate the $[q^6]$-N wavefunction in $^3He$ by imposing the condition that the calculated $^3He$ charge form factor must be consistent with what is predicted by the conventional nuclear model. The upper bound of the predicted total cross sections of $γ+ ^3He \rightarrow [q^6]_{J/Ψ} +N$ is about 2 - 4 pico-barn, depending on the model of $γ+N \rightarrow J/Ψ+N$ used in the calculations. Our results call for the need of precise measurements of $γ+p \rightarrow J/Ψ+p$ and also the $γ+^2H\rightarrow J/Ψ+n + p $ reactions near the threshold.

description: This paper presents an approach for a precise 2D-localization of a mobile station in indoor scenarios using a single base station only. In the approach both, the Direction of Arrival (DoA) and the Time of Arrival (ToA), are estimated using ultra-wideband (UWB) beamformers at both sides of the link. The article describes the algorithm, as well as the required hardware which among these are dual-linear polarized, directive UWB antenna arrays and an UWB-beam-forming network, based on finite impulse response-filters (FIR-filters) which permits the steering of the beamformer.

description: Wound healing is essential for the restoration of the barrier function of the skin. During this process, cells at the wound edges proliferate and migrate, leading to re-epithelialization of the wound surface. Wound healing assays are used to study the molecular mechanisms of wound repair, as well as in the investigation of potential therapeutics and treatments for improved healing. Numerous models of wound healing have been developed in recent years. In this review, we focus on in vitro assays, as they allow a fast, cost-efficient and ethical alternative to animal models. This paper gives a general overview of 2-dimensional (2D) cell monolayer assays by providing a description of injury methods, as well as an evaluation of each assay's strengths and limitations. We include a section reviewing assays performed in 3-dimensional (3D) culture, which employ bioengineered skin models to capture complex wound healing mechanics like cell-matrix interactions and the interplay of different cell types in the healing process. Finally, we discuss in detail available software tools and algorithms for data analysis. © 2016 by De Gruyter.

description: Purpose: This paper aims to present a method for the efficient reduction of networks modelling parasitic couplings in very-large-scale integration (VLSI) circuits. Design/methodology/approach: The parasitic effects are modelled by large RLC networks and current sources for the digital switching currents. Based on the determined behaviour of the digital modules, an efficient description of these networks is proposed, which allows for a more efficient model reduction than standard methods. Findings: The proposed method enables a fast and efficient simulation of the parasitic effects. Additionally, an extension of the reduction method to elements, which incorporate some supply voltage dependence to model the internal currents more precisely than independent current sources is presented. Practical implications: The presented method can be applied to large electrical networks, used in the modelling of parasitic effects, for reducing their size. A reduced model is created which can be used in investigations with circuit simulators requiring a lowered computational effort. Originality/value: Contrary to existing methods, the presented method includes the knowledge of the behaviour of the sources in the model to enhance the model reduction process. © Emerald Group Publishing Limited 0332-1649.
Extracting the shear viscosity of the quark-gluon plasma from flow in ultra-central heavy-ion collisions

description: We propose a method for extracting the shear viscosity over entropy density ratio (eta/s) of the quark-gluon plasma from experimental data. We argue that uncertainty due to poor knowledge of the earliest stages of a heavy-ion collision is smallest for ultra-central events. The most precise value of eta/s can thus be obtained from a global fit to p_T-integrated Fourier harmonics of azimuthal correlations. We further outline a method for quantifying the overall uncertainty in the extracted value. Only after a comprehensive and systematic accounting of all sources of uncertainty can a reliable measurement be claimed. In these proceedings we report preliminary results; full and final results will be presented in a separate publication.

description: Neben der Identifizierung von Aromastoffen durch die molekulare Sensorik sind die Aufklärung ihrer ‧Biosynthese sowie ihre biotechnische Produktion ins Zentrum der Aromastoffforschung gerückt. Geruch und Geschmack vermitteln die Qualität eines Lebensmittels. Den Geruch bestimmen flüchtige Aromastoffe, die heute vielen industriell hergestellten Lebensmitteln zugesetzt werden, um herstellungsbedingte Verluste auszugleichen oder das Aroma abzurunden. Der Verbraucher akzeptiert dabei eher natürliche Aromen. Der Begriff „natürlich“ darf nach EU-Recht allerdings nur dann zur Bezeichnung eines Aromas verwendet werden, wenn es ausschließlich Aromaextrakte oder natürliche Aromastoffe enthält.1) Dazu zählen biotechnisch erzeugte Aromastoffe, die in puncto Nachhaltigkeit für Aromenhersteller eine Alternative sind zu den klassischen natürlichen Aromen aus pflanzlichen Rohstoffen wie ätherischen Ölen. Biotechnische Verfahren dienen vermehrt dazu, strukturell komplexe Aromastoffe billiger und in größeren Mengen herzustellen, als dies mit chemischen Synthesen oder durch Pflanzenextraktion möglich ist.2) Fortschritte in Enzymtechnik, Gentechnik, Bioprozess-Monitoring und Produktisolierung bieten viel versprechende Möglichkeiten für biotechnische Aromastoffproduktion.3) Spezifische Strategien sind hierfür aber nur dann weiterzuentwickeln, wenn Enzymologie und Regulation der Aromastoffbiosynthese auf molekularer Ebene verstanden sind. Daher ist die biochemische Forschung zur Aufklärung von Biosynthesewegen in Pflanzen ein wichtiger Bestandteil der Aromabiotechnik.
Pseudogap Effects of Fermi Gases in the Presence of A Strong Effective Magnetic Field

description: We address the important question of how to characterize the normal state of fermionic superfluids under the influence of a strong effective magnetic field, implemented through rapid rotation or novel artificial field techniques. We consider the effects of crossing from BCS to BEC and the role of non-condensed pairs, or pseudogap effects. Using a simple extension of Gor'kov theory we demonstrate how these pairs organize above the transition $T_c$ into precursors of a vortex configuration, which are associated with distortions of the ideal Abrikosov lattice. This non-uniform normal state appears to enable "Bose condensation" in a field which is otherwise problematic due to the effective one-dimensionality of Landau level dispersion.

description: Optical techniques are effective tools for diagnostic applications in medicine and are particularly attractive for the noninvasive analysis of biological tissues and fluids in vivo. Noninvasive examinations of substances via a fiber optic probe need to consider the optical properties of biological tissues obstructing the optical path. This applies to the analysis of the human perilymph, which is located behind the round window membrane. The composition of this inner ear liquid is directly correlated to inner ear hearing loss. In this work, experimental methods for studying the optical properties of the human round window membrane ex vivo are presented. For the first time, a comprehensive investigation of this tissue is performed, including optical transmission, forward scattering, and Raman scattering. The results obtained suggest the application of visible wavelengths (>400nm) for investigating the perilymph behind the round window membrane in future. © 2017 Society of Photo-Optical Instrumentation Engineers (SPIE).

description: Carolacton, a secondary metabolite isolated from the extracts of Sorangium cellulosum, causes membrane damage and cell death in biofilms of the caries- and endocarditis-associated bacterium Streptococcus mutans. Here, we report the total synthesis of several derivatives of carolacton. All new structural modifications introduced abolished its biological activity, including subtle ones, such as inversion of configuration at C9. However, a bicyclic bislactone derivative as well as the methyl ester of carolacton resulted in compounds with prodrug properties. Their inhibitory activity on S. mutans was proven to be based on enzymatic hydrolysis by S. mutans which provided native carolacton resulting in biofilm damage in vivo. Moreover, we demonstrate that carolacton acts also on S. gordonii, S. oralis and the periodontitis pathogen Aggregatibacter actinomycetemcomitans, causing elongated cells and growth inhibition.
