description: Diagnosis of diabetic peripheral neuropathy (DPN) is essential to prevent complications, such as the diabetic foot syndrome. Diagnosis mostly relys on a time-consuming clinical examination by standardized procedures (pinprick test, vibration perception, Tip Therm, reflexes, muscle function). Furthermore, investigator-related bias confounds findings. To explore the potentials of a video game-based approach to diagnose polyneuropathy, a gaming platform (“Gamidiagnostics”) was set up. Participants utilized pressure sensor- equipped insoles as control units and played four games that were specifically designed to test for reaction time, sensation, skillfulness, endurance, balance, and muscle strength. A pilot study with 71 healthy volunteers and 112 patients diagnosed with DPN by clinical examination (neuropathy deficit score, NDS) evaluated the feasibility of this approach. Unbiased training of prediction algorithms with data sets identified 15 independent variables with discriminatory functions that indicated DPN. In age-matched cohorts, the support vector machines achieved a training accuracy of 87.8% (AUC-ROC 0.91) and an adjusted accuracy of 85.2% on a held- out testing data set (sensitivity 92.6%, specificity 77.8%). Distinct variables were identified for each nerve fiber deficit and allowed correct classification with adjusted accuracies of 88.1%, 91.9%, and 95.3% for Achilles tendon reflex, Aδ-/C-fiber, and Aβ-fiber impairment, respectively. Thus, a video game-based approach with smart footwear sensors was able to diagnose advanced peripheral nerve malfunction with high accuracy. This was set up in an examiner- independent manner and may be established as telemedical device.

description: Ice-rich yedoma-dominated landscapes store con-
siderable amounts of organic carbon (C) and nitrogen (N)
and are vulnerable to degradation under climate warming.
We investigate the C and N pools in two thermokarst-affected
yedoma landscapes – on Sobo-Sise Island and on Bykovsky
Peninsula in the north of eastern Siberia. Soil cores up to 3 m
depth were collected along geomorphic gradients and anal-
ysed for organic C and N contents. A high vertical sampling
density in the profiles allowed the calculation of C and N
stocks for short soil column intervals and enhanced under-
standing of within-core parameter variability. Profile-level C
and N stocks were scaled to the landscape level based on
landform classifications from 5 m resolution, multispectral
RapidEye satellite imagery. Mean landscape C and N storage
in the first metre of soil for Sobo-Sise Island is estimated to
be 20.2 kg C m −2 and 1.8 kg N m −2 and for Bykovsky Penin-
sula 25.9 kg C m −2 and 2.2 kg N m −2 . Radiocarbon dating
demonstrates the Holocene age of thermokarst basin de-
posits but also suggests the presence of thick Holocene-
age cover layers which can reach up to 2 m on top of in-
tact yedoma landforms. Reconstructed sedimentation rates
of 0.10–0.57 mm yr −1 suggest sustained mineral soil accu-
mulation across all investigated landforms. Both yedoma and
thermokarst landforms are characterized by limited accumu-
lation of organic soil layers (peat).
We further estimate that an active layer deepening of
about 100 cm will increase organic C availability in a sea-
sonally thawed state in the two study areas by ∼ 5.8 Tg
(13.2 kg C m −2 ). Our study demonstrates the importance of
increasing the number of C and N storage inventories in ice-
rich yedoma and thermokarst environments in order to ac-
count for high variability of permafrost and thermokarst en-
vironments in pan-permafrost soil C and N pool estimates.

description: Flash floods are caused by intense rainfall events and represent an insufficiently understood phenomenon in Germany. As a result of higher precipitation intensities, flash floods might occur more frequently in future. In combination with changing land use patterns and urbanisation, damage mitigation, insurance and risk management in flash-flood-prone regions are becoming increasingly important. However, a better understanding of damage caused by flash floods requires ex post collection of relevant but yet sparsely available information for research. At the end of May 2016, very high and concentrated rainfall intensities led to severe flash floods in several southern German municipalities. The small town of Braunsbach stood as a prime example of the devastating potential of such events. Eight to ten days after the flash flood event, damage assessment and data collection were conducted in Braunsbach by investigating all affected buildings and their surroundings. To record and store the data on site, the open-source software bundle KoBoCollect was used as an efficient and easy way to gather information. Since the damage driving factors of flash floods are expected to differ from those of riverine flooding, a post-hoc data analysis was performed, aiming to identify the influence of flood processes and building attributes on damage grades, which reflect the extent of structural damage. Data analyses include the application of random forest, a random general linear model and multinomial logistic regression as well as the construction of a local impact map to reveal influences on the damage grades. Further, a Spearman's Rho correlation matrix was calculated. The results reveal that the damage driving factors of flash floods differ from those of riverine floods to a certain extent. The exposition of a building in flow direction shows an especially strong correlation with the damage grade and has a high predictive power within the constructed damage models. Additionally, the results suggest that building materials as well as various building aspects, such as the existence of a shop window and the surroundings, might have an effect on the resulting damage. To verify and confirm the outcomes as well as to support future mitigation strategies, risk management and planning, more comprehensive and systematic data collection is necessary.

description: Im Rahmen der Studie „Qualitätssicherungserfassung Magenkarzinom, Kardiakarzinom, (Primärtumor)“ wurden Daten von 6279 Patienten mit operativer Therapie eines Magenkarzinoms in Deutschland vom 01.01.2007 - 31.12.2015 ausgewertet. Erfasst wurde u.a. intra- und postoperative Komplikationen, die Gesamtmorbidität, Letalität und das Langzeitüberleben. Es konnte gezeigt werden, dass höhere Tumorstadien (T4 NX M0 sowie M1 und UICC IV) in dem gesamten erfassten Zeitraum gesunken sind. UICC- und TNM-Stadium hatten auch einen sehr starken Einfluss auf die Überlebenswahrscheinlichkeit: je höher das Stadium desto schlechter waren die Überlebensraten. Eine leitliniengerechte neoadjuvante Chemotherapie wurde immer häufiger angewandt, es konnte jedoch keine signifikante Änderung beim Langzeitüberleben gezeigt werden. Ein deutlicher Überlebensvorteil ergab sich für Patienten, die eine D2-Lymphadenektomie erhielten. In der univariaten Auswertung waren prognoserelevante Faktoren das Alter, Notfalloperationen, Radikalität der Operation (R-Status), postoperative Komplikationen, der Nachweis einer Peritonealkarzinose sowie Fernmetastasen (M1). In unserem Patientenkollektiv ergab sich eine Krankenhausletalität von 6,0%, welche durch die o.g. prognostischen Faktoren beeinflusst wird, sowie zusätzlich durch Komorbiditäten und TNM-Stadium. Die Gesamtmorbidität lag bei 39,5%. Durch die vorliegenden Daten konnte auch die These unterstützt werden, dass Patienten von einer radikalen R0-Resektion sowie einer multiviszeralen Resektion auch bei Oligometastasierung profitieren.

description: In 802.11 WLANs, adapting the contention parameters to network conditions results in substantial performance improvements. Even though the ability to change these parameters has been available in standard devices for years, so far no adaptive mechanism using this functionality has been validated in a realistic deployment. In this paper we report our experiences with implementing and evaluating two adaptive algorithms based on control theory, one centralized and one distributed, in a large-scale testbed consisting of 18 commercial off-the-shelf devices. We conduct extensive measurements, considering different network conditions in terms of number of active nodes, link qualities and traffic generated. We show that both algorithms significantly outperform the standard configuration in terms of total throughput. We also identify the limitations inherent in distributed schemes, and demonstrate that the centralized approach substantially improves performance under a large variety of scenarios, which confirms its suitability for real deployments.

description: A generic prediction of string theory is the existence of many axion fields. It has recently been argued that many of these fields should be light and, like the well known QCD axion, lead to observable cosmological consequences. In this paper we study in detail the effect of the so-called string axiverse on large scale structure, focusing on the morphology and evolution of density perturbations, anisotropies in the cosmic microwave background and weak gravitational lensing of distant galaxies. We quantify specific effects that will arise from the presence of the axionic fields and highlight possible degeneracies that may arise in the presence of massive neutrinos. We take particular care understanding the different physical effects and scales that come into play. We then forecast how the string axiverse may be constrained and show that with a combination of different observations, it should be possible to detect a fraction of ultralight axions to dark matter of a few percent.

Charge hopping in coarse-grained simulations of gas-phase protein complexes
Creators: name: Fegan, Sarah Katherine
Publisher: name: University of British Columbia
Year: 2014

description: With the invention of gentle ionization methods such as electrospray ionization, mass spectrometry has been used as a tool for studying large protein complexes. Simulations of these gas-phase protein complexes will allow for better understanding of the dissociation mechanism and lead to methods for controlling the dissociation. Controlling the dissociation will help obtain structural information from the mass spectrometry experiments.In this work, the suitability of the MARTINI coarse-grained force field for gas-phase simulations is studied and a charge hopping algorithm is developed. Using a coarse-grained force field makes the simulations faster so that longer simulation times can be accessed. This is important because protein motions can take place on time scales of nanoseconds to milliseconds and these long times are not practical with all-atom simulations. Most molecular dynamics simulations use fixed charges, but including charge motion allows for better simulation of mobile protons.Two protein complexes are studied here, one dimer and one tetramer. Hopping rates, energies, radii of gyration, and distances within the complexes are calculated. Simulations with the cytochrome c$^{\prime}$ dimer (no charge hopping) are compared to published all-atom results. The MARTINI force field is found to be good for qualitative results, but slightly more attractive than the OPLS all-atom (for the isolated protein complex). The transthyretin tetramer is used to study the hopping algorithm. Modifications of the protein (blocking N-termini from accepting charges and adding basic sites with a tether) are also explored. The dissociation behavior of the protein complexes is controlled by the Coulomb repulsion model. Protein modifications near the N-termini show potential for controlling the dissociation.

description: Repetition Suppression (RS) beschreibt die Abschwächung neuronaler Antworten bei wiederholter Präsentation eines Stimulus. Obwohl man RS in verschiedenen Modalitäten in und Kortexarealen des Gehirns mit unterschiedlichen Messtechniken beobachten kann, bleiben (I.) die Beziehung zur initialen neuronalen Reaktion auf einen Reiz (Stimulus Response, SR) sowie (II.) die funktionelle Relevanz nicht vollständig geklärt. Traditionelle Theorien sehen RS als Folge neuronaler Adaptation. Neuere Modelle gehen von dynamisch wechselwirkenden, statistisch basierten Prozessen aus. In dieser Arbeit wurden elektrokortikographische (ECoG) Antworten auf auditorische Tonfolgen (oddball-Sequenzen) untersucht, die aus häufigen Standard- und seltenen devianten Tönen bestehen und entweder in regulärer oder irregulärer Reihenfolge präsentiert wurden. Es wurden Signale von 10 Probanden (Epilepsie-Patienten in prächirurgischer Diagnostik) untersucht. Im Ergebnis zeigten sich (I.) sowohl SR als auch RS in einem breit gestreuten Netzwerk über frontalen, temporalen und parietalen Kortexarealen, (II.) ein räumlicher und zeitlicher Unterschied zwischen der SR und der RS und (III.) eine Übereinstimmung der RS-Dynamik der Tonfolgen mit einem theoretischen Modell Bayesscher posteriorer Wahrscheinlichkeiten. Die Ergebnisse weisen (I.) auf dissoziierbare Prozesse von SR und RS hin und unterstützen (II.) die Perspektive von RS als eigenständige Entität mit einer wichtigen Funktion bei der sensorischen Gedächtnisformation.
Improving the written communication of psychoeducational recommendations : a vignette study

description: It is often the parent’s responsibility to follow through with the recommendations outlined in their child’s psychoeducational report. Yet, despite research demonstrating the importance of effective professional-client communication in fostering follow-through with recommendations, as well as low adherence rates, few studies have examined how to best communicate recommendations to parents. This is an unfortunate reality given that the recommendations are often the most crucial component of the psychoeducational report in enriching the child’s future functioning. In turn, many children’s needs are not attended to and the usefulness of the psychoeducational report is drastically diminished. In the present study, parents’ preferences for the way in which recommendations are communicated in a psychoeducational report was examined. Specifically, by developing a procedure to assist in exploring this topic and field testing different recommendation formats, we hoped to gain insight into parents’ preferences for how written recommendations are presented and communicated. Additionally, the recommendation formats influence on parent’s likelihood to adhere to recommendations was also explored. To accomplish this, a multi-stage, Vignette based, case-study design was employed which combined the Vignette technique with a survey format. Four broad themes and nine subthemes emerged from parents’ review of the different recommendation formats, including: organize recommendations into subject areas with headings, provide recommendations with detailed instructions, provide goals and explain how to monitor progress, and, make recommendations specific. Results also indicated a statistically significant difference in likelihood of adherence depending on which recommendation format was reviewed.

description: Die Prävalenz der Adipositas nimmt weltweit und in jeder Alterskategorie zu. Neben der Einschränkung der Lebensqualität führt die Adipositas zur Verschlechterung bestimmter Komorbiditäten und Begleiterkrankungen sowie zur Steigerung der Morbidität und Mortalität. Neben konservativen Therapiemaßnahmen zeigt die bariatrische und metabolische Chirurgie einen deutlichen Effekt in der Behandlung der Adipositas und ihrer Begleiterkrankungen. Die vorliegende Arbeit vergleicht den Outcome der Patienten mit Adipositas und einem BMI von über 50 kg/m 2 nach Sleeve Gastrektomie und Roux-en-Y Magenbypass. Grundlage der vorliegenden Arbeit war die „Qualitätssicherungsstudie für operative Therapie der Adipositas“ aus dem Zeitraum von 2005 bis 2019. Aspekte, wie der BMI, die Krankenhausverweildauer, die postoperative Verweildauer, die Komorbiditäten, die postoperativen Komplikationen, die Mortalität sowie die Remission der Begleiterkrankungen nach drei Jahren wurden im Rahmen der vorliegenden Arbeit berücksichtigt und analysiert. Statistisch signifikante Unterschiede ließen sich für den prozentualen Gewichtverlust (62,2% bei RYGB, 55,9% bei SG, p<0,001) und für die Komorbiditäten nachweisen. Bei Mortalität und Gesamtenkomplikationen bestanden keine signifikanten Unterschiede zwischen den beiden Gruppen.
Eistein-Podolski-Rosen paradox, non-commuting operator, complete wavefunction and entanglement

description: Einstein, Podolski and Rosen (EPR) have shown that any wave function (subject to the Schrödinger equation) can describe the physical reality completely, and any two observables associated to two non-commuting operators can have simultaneous reality. In contrast, quantum theory claims that the wave function can capture the physical reality completely, and the physical quantities associated to two non-commuting operators cannot have simultaneous reality. The above contradiction is known as the EPR paradox. Here, we unambiguously expose that there is a hidden assumption made by EPR, which gives rise to this famous paradox. Putting the assumption right this time leads us not to the paradox, but only reinforces the correctness of the quantum theory. However, it is shown here that the entanglement phenomenon between two physically separated particles (they were entangled prior to separation) can only be proven to exist with a "proper" measurement.

description: In this paper we study the cyclic cohomology of certain x-Hopf algebras: universal enveloping algebras, quantum algebraic tori, the Connes-Moscovici x-Hopf algebroids and the Kadison bialgebroids. Introducing their stable anti Yetter-Drinfeld modules and cocyclic modules, we compute their cyclic cohomology. Furthermore, we provide a pairing for the cyclic cohomology of x-Hopf algebras which generalizes the Connes-Moscovici characteristic map to x-Hopf algebras. This enables us to transfer the x-Hopf algebra cyclic cocycles to algebra cyclic cocycles.

Surveying and photogrammetry are required to achieve metric and accurate results in drawings, 2D/3D modelling and texturing. This paper presents the photogrammetric workflow from data acquisition to photorealistic 3D modelling and four heritage documentation case studies in different sites. High resolution and high accuracy photorealistic 3D models allow experts to recreate and interact virtually with cultural heritage either before, during of after intervention. Managers and information experts of cultural heritage monuments and sites should consider photogrammetric by-products not only to enrich knowledge, improve understanding and provide scientific records but to ease dissemination of heritage resources.

description: (abridged) Ram pressure can remove significant amounts of gas from galaxies in clusters, and thus has a large impact on the evolution of cluster galaxies. Recent observations have shown that key properties of ram pressure stripped tails of galaxies are in conflict with predictions by simulations. To increase the realism of existing simulations, we simulated for the first time a disk galaxy exposed to a uniformly magnetized wind including radiative cooling and self-gravity of the gas. We find that B-fields have a strong effect on the morphology of the gas in the tail of the galaxy. While in the pure hydro case the tail is very clumpy, the MHD case shows very filamentary structures in the tail. The filaments can be strongly supported by magnetic pressure and, when this is the case, the B-field vectors tend to be aligned with the filaments. The ram pressure stripping may lead to the formation of magnetized density tails that appear as bifurcated in the plane of the sky and resemble the double tails observed in ESO 137-001 and ESO 137-002. Such tails can be formed under a variety of situations, both for the disks oriented face-on with respect to the ICM wind and for the tilted ones. While this bifurcation is due to the generic tendency for the B-fields to produce very filamentary tail morphology, the tail properties are further shaped by the combination of the B-field orientation and the sliding of the field past the disk surface exposed to the wind. Magnetic draping does not strongly change the rate of gas stripping. For a face-on galaxy, the field tends to reduce the amount of stripping compared to the pure hydro case, and is associated with the formation of a magnetic draping layer on the side of the galaxy exposed to the ICM wind. For significantly tilted disks, the stripping rate may be enhanced by the ``scraping'' of the disk surface by the B-fields sliding past the ISM/ICM interface.

description: Ältere Menschen mit Krebs und ihre Partner*innen stehen aufgrund abnehmender Resilienz, Komorbiditäten und erhöhter Vulnerabilität im Zuge einer Krebserkrankung und ihrer Therapie hohen Belastungen gegenüber. Ziel der Arbeit war die Exploration der besonderen Belastungen und Bedürfnisse und unterstützender Faktoren älterer Krebspatient*innen und ihrer Partner*innen während der Zeit von Diagnosestellung bis zur Nachsorge. In qualitativer hypothesengenerierender Herangehensweise wurden insgesamt 18 Leitfaden-gestützte, teilstrukturierte Einzelinterviews geführt. Es fanden sich deutliche Hinweise auf Defizite in Aufklärung, Informationsvermittlung, adressatengerechter Kommunikation und Unterstützung. Zudem zeichnet sich Optimierungsbedarf in der Versorgung, auch sektorenübergreifend, ab. Dyadisches Copingvermögen sollte besonders in den Fokus der Versorgung gerückt werden und Unterstützungsbedarfe der Betroffenen und der Partner*innen wiederholt abgefragt werden.
description: Older people with cancer and their partners face high levels of stress due to decreasing resilience, comorbidities and increased vulnerability in the course of cancer and its therapy. The aim of the study was to explore the particular needs and burdens as well as supportive factors of older cancer patients and their partners during the period from diagnosis to aftercare. In a qualitative hypothesis-generating approach, a total of 18 guideline-based, semi-structured individual interviews were conducted. As a result, clear indications of deficits in education, information provision, communication and support appropriate to the target group have been found. In addition, there seems to be a need for optimisation in medical care, also across sectors. Thus, dyadic coping skills should be a particular focus of cancer treatments. Moreover, the support needs of those affected as well as their partners should be repeatedly taken into consideration and evaluated.

description: We give a deterministic algorithm that very quickly proves the primality or compositeness of the integers N in a certain sequence, using an elliptic curve E/Q with complex multiplication by the ring of integers of Q(sqrt(-7)). The algorithm uses O(log N) arithmetic operations in the ring Z/NZ, implying a bit complexity that is quasi-quadratic in log N. Notably, neither of the classical "N-1" or "N+1" primality tests apply to the integers in our sequence. We discuss how this algorithm may be applied, in combination with sieving techniques, to efficiently search for very large primes. This has allowed us to prove the primality of several integers with more than 100,000 decimal digits, the largest of which has more than a million bits in its binary representation. At the time it was found, it was the largest proven prime N for which no significant partial factorization of N-1 or N+1 is known.

description: The Golomb-Welch conjecture deals with the existence of perfect $e$% -error correcting Lee codes of word length $n,$ $PL(n,e)$ codes. Although there are many papers on the topic, the conjecture is still far from being solved. In this paper we initiate the study of an invariant connected to abelian groups that enables us to reformulate the conjecture, and then to prove the non-existence of linear PL(n,2) codes for $n\leq 12$. Using this new approach we also construct the first quasi-perfect Lee codes for dimension $n=3,$ and show that, for fixed $n$, there are only finitely many such codes over $Z^n$.

Experts at work : the Canadian state, North American environmentalism, and renewable energy in an era of limits, 1968-1983
Creators: name: Trim, Henry
Publisher: name: University of British Columbia
Year: 2014

description: This study examines the emergence of sustainable development and renewable energy in Canada during the 1970s and the interplay between environmental politics, state structures, and intellectual discourse which made this emergence possible. The dissertation focuses on two events, the construction of the New Alchemists’ Ark on Prince Edward Island with the help of the provincial and federal governments, and the Department of Energy, Mines, and Resources’ $600 million (in 1978 dollars) subsidy program for renewable energy. These events provide a lens into North American environmental politics, the policymaking of Pierre Elliott Trudeau’s government, and the intellectual influence of Cold War science on the early foundations of sustainability in the 1970s. I make four interconnected arguments about the nature of environmental politics, expert authority, the Trudeau government, and sustainability in this dissertation. First, the Trudeau government embraced the Cold War rationality of the 1960s and attempted to reorganize Canadian governance around objective analysis in an effort to transform policymaking into an exercise in calculation rather than political compromise. This privileging of technical and scientific knowledge that enhanced the authority of experts leads to my second argument. The state’s ability to shape discourse through ideology and policy feedbacks encouraged specific forms of environmental politics and, as a result, privileged an influential minority of environmentalists in the 1970s. Third, rather than rejecting or attacking this highly technocratic approach to policy, some environmentalists embraced it. These groups employed the technical knowledge preferred by the Trudeau government – modeling and forecasting – to conceptualize and advocate sustainable development. Fourth, government advisors worked directly with these technocratic environmentalists to champion renewables, thereby making Canadian sustainable development a co-production of government analysts and environmental advocates. Furthermore, the successes of renewable energy and sustainability in the 1970s rested upon the work of Cold War scientists, a formalist approach to rationality, and a belief in the efficacy of planning, as much as environmental concern.

description: The goal of the present paper is to derive some conditions on saturation of (strong) subadditivity inequality for the stochastic matrices. The notion of relative entropy of stochastic matrices is introduced by mimicking quantum relative entropy. Some properties of this concept are listed and the connection between the entropy of the stochastic quantum operations and that of stochastic matrices are discussed.

description: We give a polynomial time approximation scheme (PTAS) for computing the supremum of a Gaussian process. That is, given a finite set of vectors $V\subseteq\mathbb{R}^d$, we compute a $(1+\varepsilon)$-factor approximation to $\mathop {\mathbb{E}}_{X\leftarrow\mathcal{N}^d}[\sup_{v\in V}|\langle v,X\rangle|]$ deterministically in time $\operatorname {poly}(d)\cdot|V|^{O_{\varepsilon}(1)}$. Previously, only a constant factor deterministic polynomial time approximation algorithm was known due to the work of Ding, Lee and Peres [Ann. of Math. (2) 175 (2012) 1409-1471]. This answers an open question of Lee (2010) and Ding [Ann. Probab. 42 (2014) 464-496]. The study of supremum of Gaussian processes is of considerable importance in probability with applications in functional analysis, convex geometry, and in light of the recent breakthrough work of Ding, Lee and Peres [Ann. of Math. (2) 175 (2012) 1409-1471], to random walks on finite graphs. As such our result could be of use elsewhere. In particular, combining with the work of Ding [Ann. Probab. 42 (2014) 464-496], our result yields a PTAS for computing the cover time of bounded-degree graphs. Previously, such algorithms were known only for trees. Along the way, we also give an explicit oblivious estimator for semi-norms in Gaussian space with optimal query complexity. Our algorithm and its analysis are elementary in nature, using two classical comparison inequalities, Slepian's lemma and Kanter's lemma.

description: Glutaminyl-Cyclasen (QCs) sind an der Entstehung entzündlicher Erkrankungen beteiligt. In einer prospektiven Studie, in der zwei verschiedene vaskuläre Eingriffstechniken verglichen wurden, wurden die QC, deren Substrate und weitere Entzündungsparameter bestimmt. An der Studie nahmen zwei Kohorten von jeweils 14 Probanden teil, die sich einer gefäßchirurgischen OP (Bypass/Thrombendarterektomie) bzw. einer minimalinvasiven Intervention (PTA/Stentimplantation) unterzogen hatten. Die Erhöhung der CRP, für wenige Tage, als Prädiktor für Restenosen konnte bestätigt werden. Es wird vermutet, dass auch die QC-Aktivität im Serum als Prädiktor funktiert. Dabei war diese über einen längeren Zeitraum (mindestens 90 Tage) nachweisbar. Die Differenzierung in QC und isoQC sollte in Folgestudien angestrebt werden. Ebenso sind zum Nachweis einer Signifikanz höhere Patientenzahlen notwendig. Letztlich könnte möglicherweise der Einsatz von Inhibitoren der QC bei erhöhter Aktivität das Risiko der Entwicklung von Restenosen verringern.
description: Glutaminyl cyclases (QCs) are involved in the development of inflammatory diseases. In a prospective study comparing two different vascular intervention techniques, the QC, their substrates, and other inflammatory parameters were determined. Two cohorts of 14 subjects each having undergone vascular surgery (bypass/thrombendarterectomy) and minimally invasive surgery (PTA/stent implantation) respectively took part in the study. The increase in CRP for a few days as a predictor of restenosis could be confirmed. It is assumed that the QC activity in the serum also functions as a predictor. This was detectable over a longer period of time for at least 90 days. The differentiation between QC and isoQC should be looked at in follow-up studies. Likewise, higher patient numbers are required to demonstrate significance. Finally, the development of inhibitors of QC with increased activity could possibly reduce the risk of developing restenosis.

description: Rift Valley fever is a vector-borne zoonotic disease which causes high morbidity and mortality in livestock. In the event Rift Valley fever virus is introduced to the United States or other non-endemic areas, understanding the potential patterns of spread and the areas at risk based on disease vectors and hosts will be vital for developing mitigation strategies. Presented here is a general network-based mathematical model of Rift Valley fever. Given a lack of empirical data on disease vector species and their vector competence, this discrete time epidemic model uses stochastic parameters following several PERT distributions to model the dynamic interactions between hosts and likely North American mosquito vectors in dispersed geographic areas. Spatial effects and climate factors are also addressed in the model. The model is applied to a large directed asymmetric network of 3,621 nodes based on actual farms to examine a hypothetical introduction to some counties of Texas, an important ranching area in the United States of America (U.S.A.). The nodes of the networks represent livestock farms, livestock markets, and feedlots, and the links represent cattle movements and mosquito diffusion between different nodes. Cattle and mosquito (Aedes and Culex) populations are treated with different contact networks to assess virus propagation. Rift Valley fever virus spread is assessed under various initial infection conditions (infected mosquito eggs, adults or cattle). A surprising trend is fewer initial infectious organisms result in a longer delay before a larger and more prolonged outbreak. The delay is likely caused by a lack of herd immunity while the infections expands geographically before becoming an epidemic involving many dispersed farms and animals almost simultaneously.

description: Das Polyzystische Ovarsyndrom als häufigste endokrine, zu weiblicher Unfruchtbarkeit führende, Störung ist bislang ohne diagnostische Marker, jedoch ist eine differente microRNA Expression bei PCOS gegenüber gesunden Frauen bekannt. Daher wurden die Serumkonzentrationen der microRNAs miR-27b, miR-126, miR-224 und miR-372 bei Kinderwunschpatientinnen mittels qPCR untersucht. Es konnte ein signifikanter Zusammenhang zwischen den Serumlevel der microRNAs und polyzystischen Ovarien im Ultraschall sowie den miR-126-, miR-224- und miR-372-Level und der Diagnose PCOS festgestellt werden. In Granulosazellkulturen konnte nach Stimulation mit Testosteron (100 nM) oder Glukose (100 mM) keine Expressionsänderung der untersuchten microRNAs detektiert werden. Mittels Luziferasereporterassay und Western Blot konnte keine Regulation der potenziellen Zielgene Östrogenrezeptor α und Progesteronrezeptor durch miR-23a gezeigt werden.
description: Polycystic ovary syndrome as the most common endocrine disorder leading to female infertility is so far without diagnostic markers, but differential microRNA expression in PCOS compared to healthy women is known. Therefore, serum levels of microRNAs miR-27b, miR-126, miR-224 and miR-372 were investigated in infertility patients by qPCR. A significant association between these microRNA serum levels and polycystic ovaries on ultrasound and also between miR-126, miR-224 or miR-372 serum levels and a PCOS diagnosis was observed. In granulosa cell cultures, no change in expression of the studied microRNAs could be detected after stimulation with testosterone (100 nM) or glucose (100 mM). In luciferase reporter assay and Western blot analyses, no regulation of the potential target genes estrogen receptor α and progesterone receptor by miR-23a could be shown.
