Abstract
KNOWLEDGE TRANSFER STATEMENT The EU DELIVER project aims to enhance the quality of oral health care through codevelopment and coproduction of solutions together with citizens/patients, providers, and policymakers. The unique multicountry nature of the project will facilitate fast-track prototype development and testing of innovative QI approaches in select countries. Reflective learning regarding the transferability of findings between different countries and settings offers unique opportunities to drive progress toward context-specific implementation of innovative oral health care QI approaches. The collective knowledge gained from the 7 European countries involved in DELIVER can also generate knowhow for improving the quality of oral health care in other countries around the globe.

Abstract
Realistic haptic feedback is a key for virtual reality applications in order to transition from solely procedural training to motor-skill training. Currently, haptic feedback is mostly used in low-force medical procedures in dentistry, laparoscopy, arthroscopy and alike. However, joint replacement procedures at hip, knee or shoulder, require the simulation of high-forces in order to enable motor-skill training. In this work a prototype of a haptic device capable of delivering double the force (35 N to 70 N) of state-of-the-art devices is used to examine the four most common haptic rendering methods (penalty-, impulse-, constraint-, rigid body-based haptic rendering) in three bimanual tasks (contact, rotation, uniaxial transition with increasing forces from 30 to 60 N) regarding their capabilities to provide a realistic haptic feedback. In order to provide baseline data, a worst-case scenario of a steel/steel interaction was chosen. The participants needed to compare a real steel/steel interaction with a simulated one. In order to substantiate our results, we replicated the study using the same study protocol and experimental setup at another laboratory. The results of the original study and the replication study deliver almost identical results. We found that certain investigated haptic rendering method are likely able to deliver a realistic sensation for bone-cartilage/steel contact but not for steel/steel contact. Whilst no clear best haptic rendering method emerged, penalty-based haptic rendering performed worst. For simulating high force bimanual tasks, we recommend a mixed implementation approach of using impulse-based haptic rendering for simulating contacts and combine it with constraint or rigid body-based haptic rendering for rotational and translational movements.

Abstract
Virtual Reality (VR) is applied in various areas were a high User Experience is essential. The sense of Presence while being in VR and its relation to User Experience therefore form crucial aspects, which are yet to be understood. This study aims at quantifying age and gender effects on this connection, involving 57 participants in VR, and performing a geocaching game using a mobile phone as experimental task to answer questionnaires measuring Presence (ITC-SOPI), User Experience (UEQ) and Usability (SUS). A higher Presence was found for the older participants, but there was no gender difference nor any interaction effects of age and gender. These findings are contractionary to preexisting limited work which has shown higher Presence for males and decreases of Presence with age. Four aspects discriminating this study from literature are discussed as explanations and as a starting point for future investigations into the topic. The results further showed higher ratings in favor of User Experience and lower ratings towards Usability for the older participants.

Abstract
Periods of low energy supply are challenging conditions for organisms and cells during fasting or famine. Although changes in nutrient levels in the blood are first sensed by endothelial cells, studies on their metabolic adaptations to diminished energy supply are lacking. We analyzed the dynamic metabolic activity of human umbilical vein endothelial cells (HUVECs) in basal conditions and after serum starvation. Metabolites of glycolysis, the tricarboxylic acid (TCA) cycle, and the glycerol pathway showed lower levels after serum starvation, whereas amino acids had increased levels. A metabolic flux analysis with 13C-glucose or 13C-glutamine labeling for different time points reached a plateau phase of incorporation after 30 h for 13C-glucose and after 8 h for 13C-glutamine under both experimental conditions. Notably, we observed a faster label incorporation for both 13C-glucose and 13C-glutamine after serum starvation. In the linear range of label incorporation after 3 h, we found a significantly faster incorporation of central carbon metabolites after serum starvation compared to the basal state. These findings may indicate that endothelial cells develop increased metabolic activity to cope with energy deficiency. Physiologically, it can be a prerequisite for endothelial cells to form new blood vessels under unfavorable conditions during the process of angiogenesis in vivo.

Abstract
Abstract
Background
Lung cancer patients are at a particularly high risk for brain metastases, and a considerable number of affected patients succumb due to their intracranial disease. Chimeric Antigen Receptor (CAR) T-cells emerged as a powerful class of cell-based immunotherapy for hematological malignancies. However, it remains unclear whether CAR T-cells also represent a safe and effective therapeutic option for brain metastases.
Material and Methods
A fully syngeneic orthotopic cerebral metastasis model in mice was established by combining a chronic cranial window with repetitive intracerebral two-photon laser scanning microscopy. This approach enabled the in vivo characterization of red fluorescent CAR T-cells and tumor cells on a single-cell level over weeks. Intraparenchymal injection of Lewis lung carcinoma cells (expressing the tumor cell-antigen EpCAM) was performed, and CAR T-cells directed against EpCAM (EpCAMCAR T-cells) were injected into the adjacent brain parenchyma after solid brain tumors have formed.
Results
All mice had visible tumor take four days after the intracranial tumor cell injection, and rapid growth of solitary lesions was seen in the following days. No toxicities mediated by intracranially injected EpCAMCAR T-cells were encountered. In mice treated with EpCAMCAR T-cells, we initially observed substantial CAR T-cell accumulation within the tumor compared to controls (median number: 1700 versus 939 cells/mm2; p = 0.007). This was paralleled by lower velocities of EpCAMCAR T-cells, characterizing T-cell receptor (TCR)-mediated antitumor cytotoxicity due to long-lasting contacts between effector immune cells and tumor cells. Consequently, treatment with EpCAMCAR T-cells resulted in reduced tumorous growth as determined per in vivo microscopy (median tumor area on day 10: 1.8 versus 10.8 mm2; p = 0.001) and immunohistochemistry of excised brains (median tumor volume on day 10: 3.6 versus 33.2 mm3; p = 0.001). However, the number of EpCAM-directed CAR T-cells within the tumor markedly decreased during the observation period, pointing towards insufficient persistence of EpCAM-directed CAR T-cells. In line with these findings, survival was prolonged in mice receiving EpCAMCAR T-cells but long-lasting remission was rare (median survival: 15 versus 13 days; p = 0.012).
Conclusion
Our findings indicate that CAR T-cells injected into the cerebral parenchyma may induce relevant anti-tumor effects in brain metastases from lung cancer. Due to the translational nature of our study, prospective clinical cohorts appear warranted. Strategies improving the intratumoral persistence of CAR T-cells in brain metastases may be utilized to further boost the success of such promising therapy.

Abstract
We present Monte Carlo simulations of radiative transfer within the absorbers of X-ray microcalorimeters, utilizing a numerical model for the photon propagation and photon absorption process within the absorber structure. In our model, we include effects of Compton scattering off bound electrons and fluorescence. Scattered or fluorescence photons as well as Auger and photoelectrons escaping the absorber can result in partial energy depositions. By implementing a simplified description of the physical processes compared to existing comprehensive particle transport software frameworks, our model aims to provide representative results at a small computational effort. This approach makes it possible to use our model for quick assessments, parametric studies, and application in other Monte Carlo-based instrument simulators like SIXTE, a software package for X-ray astronomical instrumentation. To study the impact of the energy loss effects on the spectral response of a microcalorimeter, we apply our model to the sensors of the cryogenic X-ray spectrometer X-IFU onboard the future Athena X-ray observatory.

Abstract
There is growing evidence for sex and gender differences in the clinical manifestation and outcomes of human diseases. Human primary endothelial cells represent a useful cardiovascular model to study sexual dimorphisms at the cellular level. Here, we analyzed sexual dimorphisms of the secretome after serum starvation using HUVECs from twin pairs of the opposite sex to minimize the impact of varying genetic background. HUVECs were starved for 5 and 16 h, respectively, and proteins of the cell culture supernatants were analyzed by tandem mass spectrometry. Altogether, 960 extracellular proteins were identified of which 683 were amendable to stringent quantification. Significant alterations were observed for 324 proteins between long-term and short-term starvation and the majority were similar in both sexes. Only 5 proteins showed significant sex-specific regulation between long- versus short-term starvation. Furthermore, 19 unique proteins with significant sexual dimorphisms at the same time points of serum starvation were observed. A larger number of proteins, e.g. tissue factor inhibitor 2 (TFPI2), displayed higher levels in the supernatants of females compared to male cells after long term serum starvation that might point to higher adaptation capacity of female cells. The overall results demonstrate that male and female cells differ in their secretome. This article is protected by copyright. All rights reserved.

Pazopanib, an oral tyrosine kinase inhibitor, selectively inhibits VEGFR-1, -2 and -3, c-kit and PDGF-R resulting in inhibition of angiogenesis. This open-label randomized phase II trial (2:1) investigated the efficacy of combining pazopanib with FLO (5-fluorouracil, oxaliplatin) vs FLO alone (internal control arm) as first-line treatment in patients with advanced adenocarcinoma of the stomach and gastroesophageal junction (GEJ). Eighty-seven patients were randomized and 78 patients were eligible and evaluable (PaFLO arm 51 patients, FLO arm 27 patients). The PFS rate at 6 months (primary endpoint) was 34% in the PaFLO arm vs 30% in the FLO arm. Comparing PaFLO with FLO median PFS was 4.66 months (95% confidence interval [CI] 2.87-6.46) vs 4.47 months (95% CI 1.79-7.14) (95% CI, hazard ratio [HR] 0.96 (0.60-1.55), P = .882 [exploratory]); median OS was 10.19 months (95% CI 5.46-14.92) vs 7.33 months (95% CI 4.93-9.73), (95% CI HR 1.01 [0.62-1.65], P = .953, exploratory), disease control rate was 72% vs 59%. PaFLO was well tolerable, toxicities were slightly higher in the PaFLO arm. Major adverse events were loss of appetite, nausea, fatigue, diarrhea, neutropenia and thrombocytopenia. Adding pazopanib to chemotherapy shows signs of efficacy but no major improvement in this randomized phase 2 trial. The PFS at 6 months in both arms was lower than expected from the literature. Biomarkers identifying subgroups who benefit and novel combinations are needed. ClinicalTrials.gov: NCT01503372.

Abstract
OBJECTIVE To assess the safety and efficacy of epigallocatechin-3-gallate (EGCG) add-on to glatiramer acetate (GA) in patients with relapsing-remitting multiple sclerosis (RRMS). METHODS We enrolled patients with RRMS (aged 18-60 years, Expanded Disability Status Scale [EDSS] score 0-6.5), receiving stable GA treatment in a multicenter, prospective, double-blind, phase II, randomized controlled trial. Participants received up to 800 mg oral EGCG daily over a period of 18 months. The primary outcome was the proportion of patients without new hyperintense lesions on T2-weighted (T2w) brain MRI within 18 months. Secondary end points included additional MRI and clinical parameters. Immunologic effects of EGCG were investigated in exploratory experiments. RESULTS A total of 122 patients on GA were randomly assigned to EGCG treatment (n = 62) or placebo (n = 60). We could not demonstrate a difference between groups after 18 months for the primary outcome or other radiologic (T2w lesion volume, T1w hypointense lesion number or volume, number of cumulative contrast-enhancing lesions, percent brain volume change), or clinical (EDSS, MS functional composite, and annualized relapse rate) parameter. EGCG treatment did not affect immune response to GA. Pharmacologic analysis revealed wide ranging EGCG plasma levels. The treatment was well tolerated with a similar incidence of mostly mild adverse events similar in both groups. CONCLUSION In RRMS, oral EGCG add-on to GA was not superior to placebo in influencing MRI and clinical disease activity over 18 months. The treatment was safe at a daily dosage up to 800 mg EGCG. It did not influence immune parameters, despite indication of EGCG being bioavailable in patients. CLASSIFICATION OF EVIDENCE This study provides Class II evidence that for patients with RRMS, EGCG added to GA did not significantly affect the development of new hyperintense lesions on T2-weighted brain MRI. TRIAL REGISTRATION INFORMATION Clinical trial registration number: NCT00525668.

Abstract
OBJECTIVE To examine whether treatment with epigallocatechin gallate (EGCG) influences progression of brain atrophy, reduces clinical and further radiologic disease activity markers, and is safe in patients with progressive multiple sclerosis (PMS). METHODS We enrolled 61 patients with primary or secondary PMS in a randomized double-blind, parallel-group, phase II trial on oral EGCG (up to 1,200 mg daily) or placebo for 36 months with an optional open-label EGCG treatment extension (OE) of 12-month duration. The primary end point was the rate of brain atrophy, quantified as brain parenchymal fraction (BPF). The secondary end points were radiologic and clinical disease parameters and safety assessments. RESULTS In our cohort, 30 patients were randomized to EGCG treatment and 31 to placebo. Thirty-eight patients (19 from each group) completed the study. The primary endpoint was not met, as in 36 months the rate of decrease in BPF was 0.0092 ± 0.0152 in the treatment group and -0.0078 ± 0.0159 in placebo-treated patients. None of the secondary MRI and clinical end points revealed group differences. Adverse events of EGCG were mostly mild and occurred with a similar incidence in the placebo group. One patient in the EGCG group had to stop treatment due to elevated aminotransferases (>3.5 times above normal limit). CONCLUSIONS In a phase II trial including patients with multiple sclerosis (MS) with progressive disease course, we were unable to demonstrate a treatment effect of EGCG on the primary and secondary radiologic and clinical disease parameters while confirming on overall beneficial safety profile. CLINICALTRIALGOV IDENTIFIER NCT00799890. CLASSIFICATION OF EVIDENCE This phase II trial provides Class II evidence that for patients with PMS, EGCG was safe, well tolerated, and did not significantly reduce the rate of brain atrophy.

Abstract
Flow coefficients v_{n} of the orders n=1-6 are measured with the High-Acceptance DiElectron Spectrometer (HADES) at GSI for protons, deuterons, and tritons as a function of centrality, transverse momentum, and rapidity in Au+Au collisions at sqrt[s_{NN}]=2.4 GeV. Combining the information from the flow coefficients of all orders allows us to construct for the first time, at collision energies of a few GeV, a multidifferential picture of the angular emission pattern of these particles. It reflects the complicated interplay between the effect of the central fireball pressure on the emission of particles and their subsequent interaction with spectator matter. The high precision information on higher order flow coefficients is a major step forward in constraining the equation of state of dense baryonic matter.

Wrist at risk? - Considerations derived from a novel experimental setup to assess torques during hip reaming with potential implications on the orthopedic surgeons' health.

Abstract
Orthopedic surgeons endure high physical stresses when performing surgery, as large forces and torques are applied commonly. Occupational risks are consequently higher when compared to other surgical disciplines. One example is the reaming of the acetabula during total hip arthroplasty, using customized instruments. This surgery may predispose the surgeon to overuse-related wrist pathology. In this study, torques acting along the reaming tool were measured, and the resulting forces applied to the orthopedic surgeons' wrists were estimated based on the measured torque data from hip reaming. Different reamer sizes and tool velocities were analyzed to determine how both parameters may influence the torques applied at the surgeon's wrist. Using a highly standardized setup, torques were measured while the reamer was pushed into the acetabula to remove cartilage. Maximum torques and stoppage torques at blocking of the reamer were compared between feed rates and reamer sizes. Peak values of the maximum torques along the reamer axis averaged 1.5-1.8 Nm. No significant difference between maximum torques and reamer sizes was found. A significant difference in maximum torques was noted between feed rates with a large effect (p = 0.010; η2 = 0.214) and a large interaction effect (p = 0.017; η2 = 0.186). Based on this experimental setup, it can be hypothesized that the impulsive behavior of the torque when the milling tool reaches the subchondral lamella could potentially contribute to wrist pathology. These preliminary data warrant further study. Consequently, torque limiters should be implemented in reamers to minimize the risk of occupation-related pathology to the wrist.

Abstract
Radiative transition of an excited baryon to a nucleon with emission of a virtual massive photon converting to dielectron pair (Dalitz decays) provides important information about baryon-photon coupling at low q2 in timelike region. A prominent enhancement in the respective electromagnetic transition Form Factors (etFF) at q2 near vector mesons ρ/ω poles has been predicted by various calculations reflecting strong baryon-vector meson couplings. The understanding of these couplings is also of primary importance for the interpretation of the emissivity of QCD matter studied in heavy ion collisions via dilepton emission. Dedicated measurements of baryon Dalitz decays in proton-proton and pion-proton scattering with HADES detector at GSI/FAIR are presented and discussed. The relevance of these studies for the interpretation of results obtained from heavy ion reactions is elucidated on the example of the HADES results.

Abstract
e24137 Background: Parenteral nutrition is used in cancer patients (pts) requiring intensive nutrition support due to insufficient dietary intake and consuming tumor disease. As there is no data of HPN in pts with migrant background (MB), this observational study examined viability of HPN, influence on QoL and nutrition status of cancer pts with and without MB. Methods: Eligibility included ECOG ≥ 1, life expectancy ≥ 4 weeks, first time HPN for at least 28 days and written informed consent. Migrant background status and patient characteristics were assessed at baseline. At day 1 (baseline), day 14 and day 28 validated questionnaires assessed QoL, nutrition status (EORTC-QLQ-C15-PAL, Subjective global assessment (SGA)), as well as feasibility and complications of HPN. Additionally, bioimpedance analysis, BMI and weight were measured to evaluate response of HPN. Results: Between Mai 2015 and November 2019, 68 pts were included, 17 of them with MB. Tumor entities were gastric (n = 41), esophageal (n = 20) and other (n = 7), treated in a curative (n = 14) or palliative (n = 54) concept. Overall, 40 pts were able to continue HPN until day 14, 26 pts until day 28. 42 pts left study due to death (1 with MB/8 overall), worsening of general condition (3/15), dietary improvement (1/2), change of supplier (1/5), informed consent withdrawal (0/1) and lost to follow up (2/11). Global QoL in all pts was stable from baseline to d14 (n = 36; 36.6 to 40.3), whereas QoL in pts with MB deteriorated (n = 9; 37.0 to 27.8). From baseline to d28, QoL in all pts improved (n = 23; 38.4 to 47.8) and in pts with MB QoL was stable (n = 7; 40.5 to 42.9). Medical problems associated with HPN occurred in 4/11 pts with MB (36%) and 11/37 pts without MB (30%), respectively. The majority of pts reported about HPN-associated organizational complications, whereas there is no significant difference of pts with MB (6/10) and without MB (20/38). SGA improvement was observed in all pts regardless of MB. During the course of HPN, there was no significant change in body weight and BMI in all pts, independent from MB. Conclusions: Overall, 59% of pts received HPN for 14 days, only 38% of pts for 28 days. Discontinuation was mainly due to disease progression. Feasibility and organizational problems did not affect duration of HPN. Assessing HPN prospectively shows, that defining the ideal point to start HPN appears to be essential for response to HPN. In our study, migrant background is not associated with a major difference in incidence of complications, viability, benefit or duration of HPN.

Abstract
Improvement of endothelial function represents a major health effect of tea in humans. Ex vivo, tea and tea polyphenols stimulate nitric oxide (NO)-dependent vasodilation in isolated blood vessels. However, it was reported that polyphenols can generate reactive oxygen species (ROS) in vitro. We therefore aimed to elucidate the role of ROS production in tea polyphenol-induced vasodilation in explanted aortic rings. Vasorelaxation of rat aortic rings was assessed in an organ chamber model with low concentrations of epigallocatechin-3-gallate (EGCG), theaflavin-3,3'-digallate (TF3), and with green and black tea, with or without pretreatment with catalase or superoxide dismutase (SOD). The stability of EGCG and TF3 was measured by HPLC, and the levels of hydrogen peroxide (H2O2) were determined. EGCG and green tea-induced vasorelaxation was completely prevented by catalase and slightly increased by SOD. TF3 and black tea yielded similar results. Both EGCG and TF3 were rapidly degraded. This was associated with increasing H2O2 levels over time. Hydrogen peroxide concentrations produced in a time range compatible with tea polyphenol decay induced NO-dependent vasodilation in aortic rings. In conclusion, tea polyphenol-induced vasodilation in vitro is mediated by low levels of H2O2 generated during compound decay. The results could explain the apparent lack of vasodilatory effects of isolated tea polyphenols in humans.

Abstract
We report on the design, construction, and characterization of a 10 m-long high-performance magnetic shield for very long baseline atom interferometry. We achieve residual fields below 4 nT and longitudinal inhomogeneities below 2.5 nT/m over 8 m along the longitudinal direction. Our modular design can be extended to longer baselines without compromising the shielding performance. Such a setup constrains biases associated with magnetic field gradients to the sub-pm/s2 level in atomic matterwave accelerometry with rubidium atoms and paves the way toward tests of the universality of free fall with atomic test masses beyond the 10-13 level.

Abstract
Insulator-based dielectrophoresis (iDEP) has become a powerful tool for biomicrofluidic separation and analysis because it is capable to selectively separate biological particle systems according to properties like size, material, and shape. However, it has rarely been used to solve challenging separation problems involving nonbiological particles, namely, for systems that are prone to particle agglomeration. Here, we demonstrate material-selective separation of nonbiological systems, i.e., polystyrene and gold-coated polystyrene particles of two different sizes, using iDEP at high accuracy. For this purpose, we present a method to generate fluorescent gold-coated particles. We further introduce a method to reduce the static backpressure that builds up between in- and outlet reservoir due to electroosmotic flow. Moreover, we found that particle agglomeration makes their separation impossible when conventional iDEP routines are applied. Therefore, two solutions to reduce particle agglomeration are presented: A combination of AC and DC potentials and adjustment of pH and conductivity of the suspending medium. Both approaches allow separating particles under challenging conditions such as initially low absolute particle zeta potentials and high particle concentrations. Since those conditions can also be present in biological iDEP separation processes, the results are of general value for biological and nonbiological iDEP operations.

Abstract
BACKGROUND AND AIMS Gonadal hormones are mainly thought to account for sex and gender differences in the incidence, clinical manifestation and therapy of many cardiovascular diseases. However, intrinsic sex differences at the cellular level are mostly overlooked. Here, we assessed sex-specific metabolic and functional differences between male and female human umbilical vein endothelial cells (HUVECs). METHODS Cellular metabolism was investigated by bioenergetic studies (Seahorse Analyser) and a metabolomic approach. Protein levels were determined by Western blots and proteome analysis. Vascular endothelial growth factor (VEGF)-stimulated cellular migration was assessed by gap closure. HUVECs from dizygotic twin pairs were used for most experiments. RESULTS No sex differences were observed in untreated cells. However, sexual dimorphisms appeared after stressing the cells by serum starvation and treatment with VEGF. Under both conditions, female cells had higher intracellular ATP and metabolite levels. A significant decline in ATP levels was observed in male cells after serum starvation. After VEGF, the ratio of glycolysis/mitochondrial respiration was higher in female cells and migration was more pronounced. CONCLUSIONS These results point to an increased stress tolerance of female cells. We therefore propose that female cells have an energetic advantage over male cells under conditions of diminished nutrient supply. A more favourable energy balance of female HUVECs after serum starvation and VEGF could potentially explain their stronger migratory capacity.

Abstract
Abstract
Background
Personalised Medicine is one of the hallmarks of future medicine. Sex and gender differences exist in the incidence, clinical manifestation and outcome of cardiovascular diseases. Gonadal hormones are thought to account for most of these sex differences. However, besides hormones, sexual dimorphisms at the cellular level may also contribute to physiological and pathophysiological cardiovascular differences between women and men.
Purpose
To analyse intrinsic sex differences at the cellular level, we aimed to elucidate sex-specific differences in endothelial cell migration and energy metabolism under pro-migratory conditions in male and female HUVECs. To reduce biological variability, we used HUVECS obtained from umbilical cords from twin pairs of the opposite sex. These cells are exposed in utero to the same maternal environment, and therefore represent a valuable tool to study intrinsic sex-specific differences at the cellular level.
Methods
Vascular endothelial growth factor (VEGF)-stimulated migration was determined with IBIDI migration chambers. Sex-specific levels of proteins were studied using proteome profiling. Cellular metabolism was measured by Seahorse and levels of intracellular metabolites were analysed using GC-MS based technology.
Results
Female cells showed significantly higher VEGF-induced cell migration than male HUVECs. Proteomic profiling revealed a sex-specific response to VEGF treatment. Mitochondrial respiration rate was higher in VEGF-stimulated male HUVECs compared to female cells. Whereas mean glycolytic rates did not significantly differ between sexes, the ratio of glycolysis/mitochondrial respiration after VEGF stimulation was higher in female than in male HUVECs. Female cells had higher intracellular ATP levels after serum starvation and treatment with VEGF. Under both conditions, female cells showed altered levels of metabolite pools compared to male HUVECs.
Conclusions
Higher intracellular ATP and metabolite levels in female cells after serum starvation and VEGF may contribute to the observed functional sexual dimorphisms, and may also point to an increased stress tolerance of female cells. The results of our study provide a strong argument to discriminate between male and female cells in in vitro experiments.

Abstract
We present the first observation of K^{-} and ϕ absorption within nuclear matter by means of π^{-}-induced reactions on C and W targets at an incident beam momentum of 1.7 GeV/c studied with HADES at SIS18/GSI. The double ratio (K^{-}/K^{+})_{W}/(K^{-}/K^{+})_{C} is found to be 0.319±0.009(stat)_{-0.012}^{+0.014}(syst) indicating a larger absorption of K^{-} in heavier targets as compared to lighter ones. The measured ϕ/K^{-} ratios in π^{-}+C and π^{-}+W reactions within the HADES acceptance are found to be equal to 0.55±0.04(stat)_{-0.07}^{+0.06}(syst) and to 0.63±0.06(stat)_{-0.11}^{+0.11}(syst), respectively. The similar ratios measured in the two different reactions demonstrate for the first time experimentally that the dynamics of the ϕ meson in nuclear medium is strongly coupled to the K^{-} dynamics. The large difference in the ϕ production off C and W nuclei is discussed in terms of a strong ϕN in-medium coupling. These results are relevant for the description of heavy-ion collisions and the structure of neutron stars.

Abstract
TPS4148 Background: Combination of ramucirumab and paclitaxel resembles the standard treatment option in second line therapy with improvement of response rate and overall survival (REGARD, RAINBOW). Response rates to PD-1/L1 blockade in gastro-esophageal cancer patients rank within 10–20%, whereby PD-1/L1 blockade is reported to impressively extend survival rates in responders. Trials investigating either the synergistic effect of anti-angiogenesis and anti-PD-L1 or chemotherapy combined with anti-PD-L1 are promising. Based on these data we hypothesize benefit from combining immunotherapy by checkpoint inhibition with VEGF-directed treatment and chemotherapy induced increase of immunogenicity of tumor cells. This study investigates the incorporation of PD-L1 blockade by avelumab in the second line setting by combination with the actual best second-line chemotherapy regimen in metastatic gastric cancer patients (paclitaxel+ramucirumab). Methods: The RAP trial (AIO-STO-0218, registered at ClinicalTrials.gov) is a single arm multicenter phase II trial. A total of 59 patients with metastatic or locally advanced gastric or gastro-esophageal junction adenocarcinoma, ECOG 0–1, who progressed after having received first-line therapy with platinum and fluoropyrimidine doublet with or without anthracycline, docetaxel or trastuzumab within the last six months will receive avelumab and ramucirumab on day 1, 15 and paclitaxel on day 1, 8 and 15 of a 28-day cycle until disease progression (RECIST v1.1), intolerable toxicity, withdrawal of consent or at a maximum treatment of 1 year. The primary endpoint is the overall survival rate (OSR) at 6 months. Sample size calculation is based on a Simon 2-stage design with a one-sided alpha error of 10% and a power of 80%, an expected OSR at 6 months of ≥ 65% and a 0 hypothesis ≤ 50%. Secondary endpoints include OS, OSR at 12 months, PFS, safety and tolerability, duration of response. Ethics commission approved the study protocol in January 2019. Updated patient accrual will be presented. Clinical trial information: AIO-STO-0218.

Abstract
Differences between men and women are being continuously identified in many human diseases. The underlying reasons are not yet fully understood. Beside the influence of endogenous hormones and life style, intrinsic sex-specific dimorphisms at the cellular level may also play a role. HUVECs from twin pairs of opposite sex provide an excellent tool to address the question of sex-specific differences at the molecular level. We compared for the first time protein levels of male and female HUVECs from dizygotic twins using a proteomic approach. To investigate differences under basal and stress conditions, cells were either left untreated or wounded and serum starved for different time points. Approximately 10% of all proteins monitored showed significant sexual dimorphisms in their level under the different conditions tested. The majority of the proteins displayed a higher abundance in female cells. The magnitude of the difference in protein levels between male and female cells was rather small. The most prominent differences throughout all conditions were observed for several X-chromosome encoded proteins with higher levels in female (UBA1, HDHD1) or in male cells (G6PD). Proteins involved in basic cellular processes, such as gene expression and translation (e.g. HMGN1, SRP54) displayed sex-specific levels in particular conditions only. SIGNIFICANCE: This study provides novel insights into sexual dimorphic protein levels in HUVECs from twin pairs of the opposite sex. The findings identify proteins with sex-specific differences in their levels under different cell culture conditions. The study also highlights the presence of X-chromosome encoded proteins escaping X-chromosomal inactivation. The results emphasize the need to consider the cellular sex of male and female HUVECs in in vitro experiments.

Abstract
The HADES collaboration uses the e+e− production as a probe of the resonance matter produced in collisions at incident energies of 1-3.5 GeV/nucleon at GSI. Elementary reactions provide useful references for these studies and give information on resonance Dalitz decays (R→Ne+e−). Such processes are sensitive to the structure of time-like electromagnetic baryon transitions in a kinematic range where (off-shell) vector mesons play a crucial role. Results obtained in proton-proton reactions and in a commissioning pion-beam experiment are reported and prospects for future pion beam experiments and for first hyperon Dalitz decay measurements are described. The connection with the investigations of medium effects to be continued with HADES in the next years at SIS18 and SIS100 is also discussed.

Abstract
Pyrrolizidine alkaloids (PA) are a group of secondary plant metabolites belonging to the most widely distributed natural toxins. PA intoxication of humans leads to severe liver damage, such as hepatomegaly, hepatic necrosis, fibrosis and cirrhosis. An acute consequence observed after ingestion of high amounts of PA is veno-occlusive disease (VOD) where the hepatic sinusoidal endothelial cells are affected. However, the mechanisms leading to VOD after PA intoxication remain predominantly unknown. Thus, we investigated PA-induced molecular effects on human umbilical vein endothelial cells (HUVEC). We compared the effects of PA with the effects of PA metabolites obtained by in vitro metabolism using liver homogenate (S9 fraction). In vitro-metabolized lasiocarpine and senecionine resulted in significant cytotoxic effects in HUVEC starting at 300 μM. Initial molecular effect screening using a PCR array with genes associated with endothelial cell biology showed PA-induced upregulation of the Fas receptor, which is involved in extrinsic apoptosis, and regulation of a number of interleukins, as well as of different enzymes relevant for prostanoid synthesis. Modulation of prostanoid synthesis was subsequently studied at the mRNA and protein levels and verified by increased release of prostaglandin I2 as the main prostanoid of endothelial cells. All effects occurred only with in vitro-metabolically activated PA lasiocarpine and senecionine. By contrast, no effect was observed for the PA echimidine, heliotrine, lasiocarpine, senecionine, senkirkine and platyphylline in the absence of an external metabolizing system up to the highest tested concentration of 500 μM. Overall, our results confirm the metabolism-dependent toxification of PA and elucidate the involved pathways. These include induction of inflammatory cytokines and deregulation of the prostanoid synthesis pathway in endothelial cells, linking for the first time PA-dependent changes in prostanoid release to distinct alterations at the mRNA and protein levels of enzymes of prostanoid synthesis.

Abstract
131I labelled F (ab’)2 fragments of monoclonal antibodies against CA 19-9 and CEA (“radioimmunococktail” IMACIS 1) were used in a prospective study (n = 60 patients) and in a retrospective study (n = 32 patients) for the detection of colorectal carcinomas (n = 67) and other gastrointestinal CEA/CA 19-9-producing tumors (n = 32). Sensitivity was 82% and specificity 90%. Immunoscintigraphy proved useful and complementary to CT scan and sonography, especially in the diagnosis of pelvic recurrences and intra-abdominal metastases. In addition, monoclonal antibody OC 125 (IMACIS 2) was used for the detection of ovarian carcinomas (n = 10) and other CA 125 producing tumors. Immunoscintigraphy was positive in all patients (n = 18) suggesting that this radioimmunological approach could be of use in the staging, therapeutic control and earlier diagnosis of recurrent epithelial ovarian carcinoma.

Abstract
Development of the hybridoma technique has made the identification of several new tumor antigens possible. Although it was hoped that they would be more tumor-specific, none of these markers are found exclusively in tumor or in serum of tumor patients. Compared with carcinoembryionic antigen (CEA) and liver function tests, the roles of these markers (CA 19-9, CA 125, CA 15-3) were prospectively evaluated in 115 patients with colorectal liver metastases. Patients were classified according to tumor volume (T1 <25%, T2 25-75%, T3 >75%), and the extension of infiltration (solitary/multiple/diffuse; unilateral, bilateral). Patients with benign liver or biliary disease served as a control group (n=63). Overall sensitivity was 87% for *1 , 50% for *2 and 38% for *3 , with a significant correlation with tumor size. CEA serum levels were elevated in 88% of all patients. CA 19-9 was less sensitive: positive in 59%. Because of some complementary elevations, the combined use of CEA, CA 19-9 and CA 125 raised sensitivity to 94%. CA 19-9 and LDH could be useful for confirmation because of their higher specificity; however, the specificity of CEA rose to 93% on using a cut-off of 10 ng/ml instead of 3 ng/ml. The results indicate that CEA and CA 19-9 as well as liver function tests are helpful for preoperative staging in conjunction with imaging procedures before liver resection or regional chemotherapy.

Abstract
Defibrotide, a polydesoxyribonucleotide derivative with antithrombotic and fibrinolytic activity, capable of inducing the release of PGI2 from vascular endothelia, was proposed as an alternative to standard heparin coverage during blood dialysis for patients at risk of bleeding. The original procedure featured the preliminary washing of the dialysis circuit with heparin, which was then recirculated and eliminated, and the two drugs, heparin and defibrotide, are known to interact with each other. The purpose of this present study was to explore the ex-vivo heparin activity (assessed as anti-Xa activity) in diverse hemodialysis models using defibrotide (800 mg intravenous, in 4 bolus injections) and various dosages of heparin. Anti-Xa activity is negligible in dialysis conducted with defibrotide alone. When the circuit was prewashed with heparin (5000 and 2500 IU), there was evident anti-Xa activity (0.3-0.5 U/ml) in the first 30-60 minutes of dialysis; continuous heparin infusion (500 U/hour) resulted in high anti-Xa activity levels at the end of dialysis. Thus the best hemodialysis procedure for patients at high risk of bleeding should be one utilizing only defibrotide, or defibrotide plus small amounts of calcium heparin infused at the rate of 500 U/hour for not more than two hours.

Abstract
In vitro, the gaseous phase of cigarette smoke is known to induce both isomerization and degradation of dietary carotenoids, such as β-carotene and lycopene. However, the effects of cigarette smoke on the composition of circulating lycopene in vivo are not well understood. In this study, we examined the lycopene profiles of plasma from non-smokers and smokers. No oxidative intermediates of lycopene that have been observed previously in vitro were detected in the plasma, but evidence of isomerization of the carotenoid was seen. Four geometric forms of lycopene were detected in the plasma of both smokers and non-smokers, namely the (5Z), (9Z), (13Z) and (all-E) forms. The relative amounts of these isomers differed between the two cohorts and there was a significant difference (p < 0.05) between smokers and non-smokers for the ratio of total-Z:all-E lycopene, and in the relative amounts of (13Z) and (all-E)-lycopene. The ratio of (all-E):(13Z)-lycopene was 0.84:1.00 in smokers compared to 1.04:1.00 in non-smokers. In smokers, the (13Z)-isomer was generated in preference to the more thermodynamically stable (5Z) and (9Z)-isomers. This mirrors the scenario seen in vitro, in which the formation of (13Z)-lycopene was the main isomer that accompanied the depletion of (all-E) lycopene, when exposed to cigarette smoke. The results suggest that the relative amount of (13Z)-lycopene could be used as an indicator of oxidative damage to lycopene in vivo.

Abstract
Loosening of the anchorage in the bone is a problem in hip-joint arthroplasty which up to now has not been entirely solved. In the loosened condition, anchorage stems of artificial joints are subject to alternating overload which causes rupture if the fatigue strength is exceeded by the stress amplitude. At Sulzer a hip-joint anchorage stem made from wrought CoNiCrMo alloy Protasul-10 has been developed which has substantially higher fatigue strength than stems made from stainless steel of grade AISI-316L or CoCrMo cast alloy. It is therefore essentially safe from fatigue cracking and this offers the possibility of significantly easier removal in case of re-operation after loosening. This paper deals with some rules to be observed in choice or development of materials for long-term implants subject to fatigue. The results of laboratory investigations on the fatigue behaviour of cobalt-base alloys for surgical implants are discussed.

Abstract
Trans-placental cell trafficking is a naturally occurring process during pregnancy that results in the direct recognition of foreign maternal antigens by fetal tissue and vice versa. Immigration of potentially harmful allo-reactive maternal T cells into fetal circulation may provoke anti-fetal immune responses. However, the contact with fetal tissue may favor differentiation of maternal immune cells into cells with a regulatory phenotype. Human Umbilical Vein Endothelial Cells (HUVECs) possess immune-regulating properties and are one of the first fetal cells to get in contact with foreign maternal immune cells. Therefore, here we studied whether HUVECs induce the conversion of maternal T cells into regulatory T (Treg) cells. Moreover, we assessed whether this response is changing according to the sex of the HUVECs. Both female and male HUVECs induced the conversion of maternal T cells into Treg cells which is partially mediated via TGF-β. Female HUVECs showed a stronger capacity to induce Treg cells compared to male HUVECs. Our findings propose that HUVECs contribute to fetal-maternal tolerance by the increase of the Treg cell population. Sex-specific differences in Treg cell induction may partly account for the disparities on the incidence of infectious and autoimmune diseases between both sexes during early childhood.

Abstract
We investigated properties of an (In(x)Ga(1-x))2O3 thin film with laterally varying cation composition that was realized by a large-area offset pulsed laser deposition approach. Within a two inch diameter thin film, the composition varies between 0.01 ≤ x ≤ 0.85, and three crystallographic phases (cubic, hexagonal, and monoclinic) were identified. We observed a correlation between characteristic parameters of Schottky barrier diodes fabricated on the thin film and its chemical and structural material properties. The highest Schottky barriers and rectification of the diodes were found for low indium contents. The thermal stability of the diodes is also best for Ga-rich parts of the sample. Conversely, the series resistance is lowest for large In content. Overall, the (In(x)Ga(1-x))2O3 alloy is well-suited for potential applications such as solar-blind photodetectors with a tunable absorption edge.
