Inhibitions of HMGB1 and TLR4 alleviate DINP-induced asthma in mice
Authors: Hwang Yun-Ho , Lee Yongjin , Paik Man-Jeong , Yee Sung-Tae
Published: June 2019

We studied the effects of high mobility group box chromosomal protein 1 (HMGB1) and toll-like receptor (TLR4) in diisonoyl phthalate (DINP)-induced asthma. Mice with DINP-induced asthma were treated with a TLR4-signaling inhibitor or anti-HMGB1 antibody, and various markers of asthma were measured 24 h later. DINP increased airway hyperresponsiveness, numbers of cells in BALF, numbers of inflammatory cells (leukocytes, lymphocytes, monocytes, eosinophils, neutrophils, basophils) in blood, mucus production, pulmonary fibrosis, Th2 type cytokine levels in BALF, and lung cell apoptosis. On the other hand, administrations of TLR4-signaling inhibitors (TAK-242) or anti-HMGB1 antibodies to a mouse model of DINP-induced asthma reduced biological markers of asthma. These results show TLR4 and HMGB1 both contribute to DINP-induced asthma, and that the inhibitions of TLR4 or HMGB1 offer potential means of treating asthma induced by phthalates like DINP.
Revisiting hypoxia therapies for tuberculosis
Authors: Oehlers Stefan H.
Published: June 2019

The spectre of the coming post-antibiotic age demands novel therapies for infectious diseases. Tuberculosis (TB), caused by Mycobacterium tuberculosis, is the single deadliest infection throughout human history. M. tuberculosis has acquired antibiotic resistance at an alarming rate with some strains reported as being totally drug resistant. Host-directed therapies (HDTs) attempt to overcome the evolution of antibiotic resistance by targeting relatively immutable host processes. Here, I hypothesise the induction of hypoxia via anti-angiogenic therapy will be an efficacious HDT against TB. I argue that anti-angiogenic therapy is a modernisation of industrial revolution era sanatoria treatment for TB, and present a view of the TB granuloma as a ‘bacterial tumour’ that can be treated with anti-angiogenic therapies to reduce bacterial burden and spare host immunopathology. I suggest two complementary modes of action, induction of bacterial dormancy and activation of host hypoxia-induced factor (HIF)-mediated immunity, and define the experimental tools necessary to test this hypothesis.
Preliminary Design of the Two-Phase Ejector under Constant Area Mixing Assumption for 5 kW Experimental System
Authors: Atmaca Ayşe Uğurcan , Erek Aytunç , Ekren Orhan
Published: June 2019

Ejector expansion refrigeration cycle is the modification of the vapour compression refrigeration cycle with the implementation of a two-phase ejector and a vapour-liquid separator to improve the cycle performance. In this study, main geometrical parameters of an ejector, i.e. diameters of the motive nozzle throat, motive nozzle outlet, suction nozzle outlet, and constant area mixing section are calculated in order to provide the preliminary design aspects at various operation conditions. The thermodynamic model of the ejector is established with reference to constant-area mixing assumption. The equations are solved in Matlab®. The environmentally-friendly refrigerants, R1234yf and R1234ze(E) from the hydrofluoroolefins (HFOs) and R134a which is about to be phased out by the F-gas Regulation are used in the analyses. When compared to the previous literature findings, the current research aims to compare the dimensions of a two-phase ejector to be used in an experimental system having 5 kW cooling capacity for these three refrigerants.
Wave Power Variation near the Romanian Coastal Waters
Authors: Onea Florin , Rusu Liliana
Published: June 2019

In the present work, the relationship between Romanian wave power and the distance to the shoreline is evaluated, by taking also into account the performances of some wave energy converters. Several reference sites located on northern, centre and southern part of this area were taken into account, the wave energy being assessed at 5 km, 15 km and 30 km from the shore. More important resources were noticed close to the Vama Veche (in south) were an average of 4.27 kW/m is reported offshore. As we go from shore to offshore, the wave variations may reach a maximum of 7.7% in the case of the Navodari site (centre), while a 3.3% is expected for Vama Veche. In the case of the wave generators, three types of systems (Seabased, Pelamis and Wave Dragon) were considered, that cover a rated capacity ranging from 15 kW to 7000 kW. For the Saint George s ite (north), the power production is insignificant being located close to zero, while in terms of the capacity factor a maximum of 0.12% may be expected from the Seabased system. The capacity factor significantly increases as we go to south, being reported during winter time values close to 3% for Pelamis system or 6% in the case of Seabased, respectively.

Authors: Gauzzi Paolo , Perez del Rio Elena
Published: June 2019

The KLOE-2 Collaboration succesfully ended its data-taking collecting a total integrated luminosity of 5.5 fb−1 at the peak of the φ(1020) resonance at the DAΦNE collider of the Frascati LNF. New detectors have been added to the KLOE apparatus to improve the detector acceptance, the tracking capability, and also to be able to tag the scattered electrons in γγ processes. By summing the new data sample to the old one of the previous KLOE data-taking ended in 2006, a total of about 8 fb−1 has been collected, corresponding to 24 billions of φ produced. The measurement program of KLOE-2 includes precision studies on kaon and other light mesons, hadronic cross-section, and dark force searches.

Methods of parameterization of amplitudes and extraction of resonances, D-decay amplitudes
Authors: Kamiński Robert
Published: June 2019

Amplitudes used for analyses of two-body interactions very often are not unitary therefore can not guarantee correct results. It is, however, quite easy to construct unitary amplitude or check whether given amplitude fulfills unitarity condition. Only few conditions must be fulfilled to guarantee unitarity. Presently, when in many data analyses very small, overlapping or broad signals are studied, non-unitary effects can significantly influence results and lead to nonphysical interpretation of obtained parameters.
Comment on the X(3915) nonstandard hadron candidate
Authors: Olsen Stephen Lars
Published: June 2019

I review the experimental evidence for the X(3915), the candidate nonstandard meson associated with ωJ/ψ resonance-like peaks in B → KωJ/ψ and γγ → ωJ/ψ near M(ωJ/ψ) = 3920 MeV, and address the conjecture that it can be identified as the χ′c2, the radial excitation of the χc2 charmonium state. Since the partial decay width for B → KX(3915) is at least an order-of-magnitude higher than that for B → Kχc2, its assignment as the χ’c2 is dubious.

Meson decay studies from MAMI A2
Authors: Heijkenskjöld Lena
Published: June 2019

Decays of the light mesons π0, η, ω, and η’ provide a unique laboratory to test fundamental aspects of hadron physics. Precision studies of such diverse topics as the light quark mass ratio, π−π scattering lengths, and searches for physics beyond the Standard Model are possible. Additionally, Dalitz decays of light mesons provide a way of measuring the electromagnetic meson transition formfactors in the time-like region.

The A2 tagged photon facility at the Mainz Microtron provides a high yield of light mesons produced by photo-induced reactions on protons, which makes the experiment ideal for high precision measurements of meson decays. Presented here are the contributions made by the A2 collaboration to such studies.

Recent results on hadron physics at KLOE-2
Authors: Curciarello Francesca
Published: June 2019

The KLOE-2 experiment at the Frascati φ−factory ended its data-taking in March 2018 collecting more than 5 fb−1 at the φ peak. The new data sample, together with the KLOE one, corresponds to 2.4 ×1010 φ and 3.1×108 η meson events. It represents the largest sample ever collected at the φ peak in e+e− colliders, allowing to study light mesons with unprecedented statistics. Recent results obtained with KLOE data on hadron physics e.g. – measurement of the running of the fine structure constant below 1 GeV, the combination of hadron cross section measurements with determination of $ a_\mu ^{\pi \pi } $, the new preliminary η → π+π− limit, and progress in γγ studies – will be presented.

Existing Monte-Carlo generators with radiative corrections to the e+e-→π+π- process are usually developed under the assumption that pions can be treated as pointlike particles. We study the e+e-→π+π-γ process with final-state radiation and test this assumption using simulated events from the MCGPJ generator based on the scalar QED hypothesis. In order to increase a fraction of events with FSR, the analysis was performed in the energy region to the left from the ρ-meson peak (660÷785 MeV) that is based on the integrated luminosity of about 8.4 pb-1. The experimental data for the photon energy spectrum agree with the simulation results at 1% level.

The light-by-light contribution from the axial-vector (AV) mesons exchanges to the muon anomalous magnetic moment is estimated in the framework of the nonlocal chiral quark model. The preliminary answer for contributions from a1 and f1 mesons to (g − 2)µ is 0.34 · 10−11 and does not support the Melnikov-Vainshtein estimate 2.2 · 10−11.
Search for dark forces at KLOE-2
Authors: Perez del Rio Elena
Published: June 2019

During the last years several Dark Sector Models have been proposed in order to address striking and puzzling astrophysical observations which fail standard interpretations.

In the minimal case a new vector particle, the so called dark photon or U-boson, is introduced, with small coupling with Standard Model particles. Also, the existence of a dark Higgs boson h’ is postulated, in analogy with the Standard Model, to give mass to the U-boson through the Spontaneous Symmetry Breaking mechanism. The discovery of such a Dark Force Mediator would belong to a new field of Physics Beyond the Standard Model.

The KLOE experiment, working on the DAΦNE e+e− collider in Frascati, searched for the existence of the U-boson in a quite complete way, investigating several diﬀerent processes and final states. Tight limits on the model parameters have been set at 90%CL. Further improvements are expected in terms of sensitivity and discovery potential with the new KLOE-2 detector working on the improved DAΦNE e+e− collider, which has collected more than 5 fb−1.
Search for Highly Ionizing Particles with the Pixel Detector at Belle II
Authors: Dort Katharina , Lange Jens Soeren , Lautenbach Klemens
Published: June 2019

The Belle II experiment, located at the SuperKEKB collider at the high-energy research facility KEK in Tsukuba, Japan, started operation in 2018. Compared to the predecessor experiment Belle, Belle II plans to increase the peak luminosity by a factor of about 40, by employing nano-beam technology in the interaction region. In particular the new, innermost sub-detector of Belle II the Pixel Vertex Detector (PXD) - is in close proximity to the interaction point. This allows for the detection of particles, which do not leave a signal in the outer sub-detectors. Among these, Highly Ionizing Particles (HIPs) encounter a characteristically high energy loss, limiting their penetration depth into the detector. Anti-deuterons and magnetic monopoles as possible HIPs are considered. Without a signal in the outer sub-detectors, no track trigger is issued, resulting in possible information loss. The possibility of identifying HIPs solely with information provided by the PXD is presented, by using neural network algorithms operating in a multidimensional parameter space of PXD cluster data.
Baryon Form Factors at BESIII

In this talk I present recent progress on the studies of baryon form factors at BESIII, including the measurements of the time-like proton electromagnetic form factor via e+e−→ pp̅ in the center-mass-system energy region 2.0 −3.08 GeV, as well as the electromagnetic form factors of Λ and Λc, respectively. These results are followed by a short discussion about the prospects of the BESIII program in this area.
The sigma-meson exchange contribution to the muonic hydrogen Lamb shift
Authors: Dorokhov A.E. , Martynenko A.P. , Martynenko F.A. , Radzhabov A.E.
Published: June 2019

The sigma(ξ)meson exchange contribution to the potential of the muon-proton interactionin muonichydrogen inducedbythe ξ-meson coupling to two photons is estimated. The transition form factor ξ → γγ is deduced from the quark model and experimental data on the decay widths Γσγγ. It is shown that scalar meson exchange contribution to the Lamb shift in muonic hydrogen, △ELs(2P−2S ),is rather large and relevant for a comparison with coming precise experimental data.
Novel aspects of baryon-antibaryon production in e+ e- annihilations
Authors: Kupsc Andrzej
Published: June 2019

Baryon-antibaryon decays of J/ψ and ψ‘ produced at an electron-positron collider are presented as a tool to study baryon properties and to test discrete symmetries. We focus on a novel aspect of this process: the transverse polarization of the produced baryons. The polarization was observed for first time by the BESIII Collaboration in e+e→ J/ψ → ΛΛ̅ . The observed spin polarization and correlations were used for a direct determination the Λ and Λ ̅ decay asymmetries. The result for Λ → pπ−, the well known Λ polarimeter process, diﬀers by 17(3)% from the established value of 0.642(13). Finally the prospects of the method for studies of weak decays of hyperons and for CP tests in baryon sector are discussed.

We complete our derivation of upper limits on the CP violating ηππ and η‘ππ couplings from an analysis of their two-loop contribution to the neutron electric dipole moment (nEDM). As a result we obtain numerical upper limits for the ηππ and η‘ππ branchings and couplings which are important for planned experiments at JLab. We also derive upper limits on the CP violating θ̅parameter of QCD θ̅< 2.8 × 10−10

In these proceedings we review the SM prediction for the tau leptonic decays, including the radiative $ (\tau \to \ell \lambda \nu \bar \nu ) $ and the five-body $ (\tau \to \ell \ell '\ell '\nu \bar \nu ) $ decay modes, which are among the most powerful tools to study precisely the structure of the weak interaction and to constrain possible contributions beyond the V–A coupling of the Standard Model.
Recent results on Kaon Physics at KLOE-2
Authors: Di Cicco Alessandro
Published: June 2019

KLOE-2 extends the physics program of the forerunner KLOE experiment, especially in the field of discrete symmetries tests with neutral kaons. KLOE and KLOE-2 have collected together the largest sample of electron-positron collisions at an energy equal to the φ-meson mass, corresponding to about 2.4×1010 produced φ mesons.

The latest results on neutral kaon physics at KLOE will be reviewed, together with the status and prospects of the analyses of KLOE-2 data. A new measurement of the charge asymmetry in KS semileptonic decays with 1.7 fb−1 of KLOE data, which improves the sensitivity of previous measurements of about a factor two, will be presented. Furthermore, the status of the analysis devoted to directly test T and CPT symmetries in neutral kaons transitions, as well as the search of the pure CP-violating KS → 3π0 decay using part of the recently acquired KLOE-2 dataset, will be presented.
Deutsche Übersetzung und sprachliche Validierung des multidimensionalen Dyspnoe-Profils (MDP)
Authors: Stump A. , Schröder M. , Domanski U. , Franke K.-J. , Nilius G.
Published: June 2019

Hintergrund Luftnot ist als subjektive Wahrnehmung von Atembeschwerden charakterisiert. Dazu gehören verschiedene sensorische Qualitäten mit unterschiedlichen Intensitäten. Die Erfassung der verschiedenen Qualitäten und Quantifizierung gestaltet sich sehr schwierig. Bislang ist in deutscher Sprache kein validiertes Instrument zur multidimensionalen Erfassung von Luftnot verfügbar. Das Multidimensional Dyspnea Profile (MDP) wurde 2015 von Banzett et al. entwickelt, um dieser Vielschichtigkeit gerecht zu werden und diese erkrankungsübergreifend sowie zeit- oder situationsspezifisch zu erfassen.

Methodik In dieser Arbeit stellen wir die deutsche Übersetzung des MDP vor. Das Mapi Research Trust hat die deutsche Version anhand international anerkannter Richtlinien zur interkulturellen Adaption von Patientenfragebögen erzeugt. Dies beinhaltete auch eine sprachliche Validierung an betroffenen Patienten.

Ergebnisse Das Instrument misst die Intensität der allgemein durch Luftnot hervorgerufenen Unannehmlichkeit. Es prüft das Vorhandensein von 5 sensorischen, Luftnot beschreibenden Qualitäten und misst deren jeweilige Intensität. Zusätzlich wird die Intensität von 5 möglichen emotionalen Reaktionen erfasst. Die Datenerhebung erfolgt zeit- oder situationsspezifisch.

Schlussfolgerung Die Autoren stellen den Fragebogen in englischer Sprache zur freien Verfügung. Auch der deutsche Fragebogen steht zur akademischen Nutzung frei zur Verfügung und ist im klinischen Alltag und in der Forschung nutzbar. Ein Vergleich mit internationalen Studien wird möglich.
„Myocardial injury“ und Myokardinfarkt – Konsequenzen für die Klinik im Kontext aktueller Leitlinien
Authors: Wild Johannes , Wenzel Philip
Published: June 2019

Im 2018 veröffentlichten Konsensus-Papier „Universal Definition of Myocardial Infarction“ der Europäischen und der Amerikanischen Gesellschaft für Kardiologie (ESC/ACC) erfolgte eine detaillierte Unterscheidung zwischen „Myocardial injury“ und Myokardinfarkt. Für die Diagnose der „Myocardial injury“ sind hierbei allein erhöhte Troponinwerte erforderlich. Zeigen sich neben der laborchemisch messbaren Myokardschädigung auch klinische Zeichen der Ischämie, ergibt sich die Diagnose Myokardinfarkt. Eine „Myocardial injury“ kann durch eine Vielzahl an kardialen und extrakardialen Erkrankungen verursacht werden und übertrifft sogar den Myokardinfarkt, was die Mortalität betrifft. Gerade durch die Heterogenität der Ursachen stellt die „Myocardial injury“ im klinischen Alltag eine besondere Herausforderung dar.
Biochemische Marker der Myokardschädigung bei ischämischer versus nicht ischämischer Ätiologie
Authors: Magnussen Christina , Schnabel Renate B.
Published: June 2019

Biomarker sind objektiv gemessene Indikatoren physiologischer oder pathologischer biologischer Prozesse, die möglichst sensitiv, spezifisch, reproduzierbar und kosteneffektiv bestimmt werden sollten. Sie werden als Antwort auf akute myokardiale Ischämie, chronischen myokardialen Stress, Inflammation oder strukturelle Umbauprozesse freigesetzt. Die wichtigsten Biomarker in der klinischen Routine sind (hochsensitive) Troponine (akute Myokardischämie) und natriuretische Peptide (Druck-/Volumenbelastung). Strukturelle Marker (Fibrose/Remodeling) werden noch nicht routinemäßig eingesetzt.
