Abstract
Imaging intact human organs from the organ to the cellular scale in three dimensions is a goal of biomedical imaging. To meet this challenge, we developed hierarchical phase-contrast tomography (HiP-CT), an X-ray phase propagation technique using the European Synchrotron Radiation Facility (ESRF)'s Extremely Brilliant Source (EBS). The spatial coherence of the ESRF-EBS combined with our beamline equipment, sample preparation and scanning developments enabled us to perform non-destructive, three-dimensional (3D) scans with hierarchically increasing resolution at any location in whole human organs. We applied HiP-CT to image five intact human organ types: brain, lung, heart, kidney and spleen. HiP-CT provided a structural overview of each whole organ followed by multiple higher-resolution volumes of interest, capturing organotypic functional units and certain individual specialized cells within intact human organs. We demonstrate the potential applications of HiP-CT through quantification and morphometry of glomeruli in an intact human kidney and identification of regional changes in the tissue architecture in a lung from a deceased donor with coronavirus disease 2019 (COVID-19).

Abstract
Human organs are complex, three-dimensional and multiscale systems. Spatially mapping the human body down through its hierarchy, from entire organs to their individual functional units and specialised cells, is a major obstacle to fully understanding health and disease. To meet this challenge, we developed hierarchical phase-contrast tomography (HiP-CT), an X-ray phase propagation technique utilising the European Synchrotron Radiation Facility's Extremely Brilliant Source: the world's first high-energy 4 th generation X-ray source. HiP-CT enabled three-dimensional and non-destructive imaging at near-micron resolution in soft tissues at one hundred thousand times the voxel size whilst maintaining the organ's structure. We applied HiP-CT to image five intact human parenchymal organs: brain, lung, heart, kidney and spleen. These were hierarchically assessed with HiP-CT, providing a structural overview of the whole organ alongside detail of the organ's individual functional units and cells. The potential applications of HiP-CT were demonstrated through quantification and morphometry of glomeruli in an intact human kidney, and identification of regional changes to the architecture of the air-tissue interface and alveolar morphology in the lung of a deceased COVID-19 patient. Overall, we show that HiP-CT is a powerful tool which can provide a comprehensive picture of structural information for whole intact human organs, encompassing precise details on functional units and their constituent cells to better understand human health and disease.

Abstract
In microelectronics, recently developed 3D integration offers the possibility to stack the dice or wafers vertically instead of putting their different parts next to one another, in order to save space. As this method becomes of greater interest, the need for 3D imaging techniques becomes higher. We here report a study about different 3D characterization techniques applied to copper pillars, which are used to stack different dice together. Destructive techniques such as FIB/SEM, FIB/FIB, and PFIB/PFIB slice and view protocols have been assessed, as well as non-destructive ones, such as laboratory-based and synchrotron-based computed tomographies. A comparison of those techniques in the specific case of copper pillars is given, taking into account the constraints linked to the microelectronics industry, mainly concerning resolution and sample throughput. Laboratory-based imaging techniques are shown to be relevant in the case of punctual analyses, while synchrotron based tomographies offer highly resolved volumes for larger batches of samples.

Abstract
CASE REPORT A 7-year-old female spayed Labrador Retriever was managed for suspected carbamate toxicosis after confirmed ingestion of a large amount of methiocarb. Therapy included decontamination, supportive care and management for aspiration pneumonia. On the third day of hospitalisation, after an initial clinical improvement, the dog developed respiratory muscle weakness, inspiratory dyspnoea and pronounced cervical muscle weakness. These delayed clinical signs were consistent with the 'intermediate syndrome' described in some cases of organophosphate and carbamate toxicoses in humans and also described in one case of organophosphate toxicosis in the dog. Intermediate syndrome has not been reported in carbamate toxicosis in the dog. CONCLUSION This case report highlights the necessity for veterinarians to monitor for additional complications not commonly considered in acute carbamate toxicoses.

Abstract
Abstract
Background: The multicenter AVANTI observational study is evaluating the safety and effectiveness of EU-approved BEV-containing regimens (BEV + paclitaxel [PAC] or BEV + capecitabine [CAP]) as first-line therapy for HER2-negative aBC in German routine oncology practice.
Methods: Eligible patients (pts) had received no prior chemotherapy (CT) for aBC and had no BEV contraindications. CT schedule, diagnostics, and frequency of follow-up visits are at the physician's discretion. Data are collected for 1 year after starting BEV, with 6-monthly follow-up for 1.5 years thereafter. We explored treatment outcomes in pts with triple-negative aBC (TNBC), pts considered at high risk according to a simple prognostic index for OS in BEV-treated pts [Llombart, 2014], and subgroups defined by timing of BEV+CT initiation.
Results: Between Oct 2009 and Feb 2015, 2168 pts treated at 331 centers received BEV+PAC (n=1774) or BEV+CAP (n=394). Of these, 445 (21%) had TNBC and 306 (14%) met the high-risk criteria. Within the hormone receptor-positive (HR+) subgroup, pts receiving endocrine therapy (ET) before BEV+CT were older than pts starting BEV+CT immediately (median age 65 vs 60 years, respectively) and included a smaller proportion with ECOG performance status 0 (39% vs 47%), visceral metastases (70% vs 77%), or prior (neo)adjuvant CT exposure (46% vs 57%). In all subgroups, median BEV treatment duration was longer than median CT duration. At the data cutoff for this interim analysis (Mar 1, 2015), median duration of observation was 10.8 (range <0.1–47.5) months. The table shows treatment exposure and efficacy overall and in selected subgroups.

Conclusions: Interim results from this large observational study indicate that first-line BEV+CT is an effective therapy in all risk subgroups of a general population of pts with HER2-negative aBC treated in routine oncology practice, including pts with a particularly poor prognosis. Results of these exploratory subgroup analyses suggest that BEV+CT could be considered irrespective of HR status.

Abstract
Abstract
Background: In Europe, BEV is approved as first-line therapy for metastatic breast cancer in combination with either paclitaxel (PAC) or capecitabine (CAP).
Methods: The ongoing multicenter non-interventional AVANTI study aims to determine the safety and efficacy of first-line BEV–PAC or BEV–CAP in the context of routine oncology practice in Germany and to assess selection criteria that influence therapy choice. Eligible patients (pts) have previously untreated aBC and no contraindications for BEV. Chemotherapy schedule, diagnostics, and frequency of follow-up visits are at the physician's discretion. Data are collected for 1 year after the start of BEV, with 6-monthly follow-up for 1.5 years after the end of documented observation or BEV discontinuation, whichever occurs first.
Results: Between Oct 2009 and Feb 2015, 2168 pts treated at 331 German centers received BEV–PAC (N=1774) or BEV–CAP (N=394). The most common reasons driving treatment choice were efficacy (66% BEV–PAC, 60% BEV–CAP), guidelines (55% BEV–PAC, 50% BEV–CAP), and tolerability (40% BEV–PAC, 45% BEV–CAP). Compared with pts receiving BEV–PAC, the BEV–CAP subgroup included relatively fewer pts with ≥3 metastatic sites, visceral metastases, and stage IV disease at diagnosis, and relatively more pts with triple-negative aBC (TNBC) and prior (neo)adjuvant chemotherapy. At the time of data cut-off for this interim analysis (Mar 1, 2015), median duration of observation was 10.8 months (range <0.1–47.5). BEV was typically continued for longer than chemotherapy (median 5.9 months [95% CI 5.6–6.3] vs 4.6 months [95% CI 4.4–4.9], respectively). Among pts with hormone receptor-positive disease, only 9% received concurrent endocrine therapy with BEV. The most common reason for stopping treatment was disease progression (483 of 1529 [32%] who had stopped BEV–PAC; 157/345 [46%] who had stopped BEV–CAP). At data cut-off, 1245 pts (57%) had experienced a PFS event. Median PFS was 10.1 months (95% CI 9.6–10.7) overall, 10.7 months (95% CI 10.1–11.3) for BEV–PAC, and 8.1 months (95% CI 6.6–9.0) for BEV–CAP. Median PFS in clinically important subgroups was: TNBC 7.1 months (95% CI 6.2–8.0); ≥3 metastatic sites 9.7 months (8.7–11.2); anthracycline- and/or taxane-pretreated 9.2 months (8.5–9.9); ≥65 years old 9.9 months (9.1–10.7). Safety was consistent with the well-established safety profiles of the two regimens. Grade ≥3 adverse events occurred in 17% of pts (16% BEV–PAC, 18% BEV–CAP). There were no new safety signals.
Conclusions: Interim results of this large non-interventional study indicate that first-line BEV-containing regimens represent an active and well-tolerated therapy option for aBC. Data collection in non-inferiority studies based on routine clinical practice typically differs from that in prospective clinical trials. Nevertheless, these results from AVANTI suggest that the efficacy and tolerability of BEV–PAC and BEV–CAP seen in the E2100, RIBBON-1, and TURANDOT trials can be replicated in routine oncology practice. Further analyses focusing on the incidence, management, and potential risk factors for elevation of blood pressure are ongoing.

Abstract
X-ray tomography is a relevant technique for the dynamic follow-up of gas bubbles in an opaque viscoelastic matrix, especially using image analysis. It has been applied here to pieces of fermenting wheat flour dough of various compositions, at two different voxel sizes (15 and 5 μm). The resulting evolution of the main cellular features shows that the creation of cellular structures follows two regimes that are defined by a characteristic time of connectivity, tc [30 and 80 min]: first (t ≤ tc), bubbles grow freely and then (t ≥ tc) they become connected since the percolation of the gas phase is limited by liquid films. During the first regime, bubbles can be tracked and the local strain rate can be measured. Its values (10(-4)-5 × 10(-4) s(-1)) are in agreement with those computed from dough viscosity and internal gas pressure, both of which depend on the composition. For higher porosity, P = 0.64 in our case, and thus occurring in the second regime, different cellular structures are obtained and XRT images show deformed gas cells that display complex shapes. The comparison of these images with confocal laser scanning microscopy images suggests the presence of liquid films that separate these cells. The dough can therefore be seen as a three-phase medium: viscoelastic matrix/gas cell/liquid phase. The contributions of the different levels of matter organization can be integrated by defining a capillary number (C = 0.1-1) that makes it possible to predict the macroscopic dough behavior.

Abstract
Background In order to improve the clinical outcome of patients with locally advanced squamous cell carcinoma of the head and neck (LASCCHN) not being capable to receive platinum-based chemoradiation, radiotherapy can be intensified by addition of cetuximab, a monoclonal antibody that blocks the epidermal growth factor receptor (EGFR). The radioimmunotherapy with cetuximab is a feasible treatment option showing a favourable toxicity profile. The most frequent side effect of radiotherapy is radiation dermatitis, the most common side effect of treatment with cetuximab is acneiform rash. Incidence and severity of these frequent, often overlapping and sometimes limiting skin reactions, however, are not well explored. A clinical and molecular differentiation between radiogenic skin reactions and skin reactions caused by cetuximab which may correlate with outcome, have never been described before. Methods/design The HICARE study is a national, multicenter, prospective phase IV study exploring the different types of skin reactions that occur in patients with LASCCHN undergoing radioimmun(chemo)therapy with the EGFR inhibitor cetuximab. 500 patients with LASCCHN will be enrolled in 40 participating sites in Germany. Primary endpoint is the rate of radiation dermatitis NCI CTCAE grade 3 and 4 (v. 4.02). Radioimmunotherapy will be applied according to SmPC, i.e. cetuximab will be administered as loading dose and then weekly during the radiotherapy. Irradiation will be applied as intensity-modulated radiation therapy (IMRT) or 3D-dimensional radiation therapy. Discussion The HICARE trial is expected to be one of the largest trials ever conducted in head and neck cancer patients. The goal of the HICARE trial is to differentiate skin reactions caused by radiation from those caused by the monoclonal antibody cetuximab, to evaluate the incidence and severity of these skin reactions and to correlate them with outcome parameters. Besides, the translational research program will help to identify and confirm novel peripheral blood based molecular predictors and surrogates for treatment response and resistance.

Abstract
The three-dimensional (3-D) architecture of rigid multiphase networks present in AlSi10Cu5Ni1 and AlSi10Cu5Ni2 piston alloys in as-cast condition and after 4 h spheroidization treatment is characterized by synchrotron tomography in terms of the volume fraction of rigid phases, interconnectivity, contiguity and morphology. The architecture of both alloys consists of α-Al matrix and a rigid long-range 3-D network of Al(7)Cu(4)Ni, Al(4)Cu(2)Mg(8)Si(7), Al(2)Cu, Al(15)Si(2)(FeMn)(3) and AlSiFeNiCu aluminides and Si. The investigated architectural parameters of both alloys studied are correlated with room-temperature and high-temperature (300 °C) strengths as a function of solution treatment time. The AlSi10Cu5Ni1 and AlSi10Cu5Ni2 alloys behave like metal matrix composites with 16 and 20 vol.% reinforcement, respectively. Both alloys have similar strengths in the as-cast condition, but the AlSi10Cu5Ni2 is able to retain ∼15% higher high temperature strength than the AlSi10Cu5Ni1 alloy after more than 4 h of spheroidization treatment. This is due to the preservation of the 3-D interconnectivity and the morphology of the rigid network, which is governed by the higher degree of contiguity between aluminides and Si.

Abstract
An easy, rapid and economic two-step procedure is described for the detection of Salmonella/Shigella. In the first step the susceptibility of suspected colonies for the phage O-1 of FELIX and CALLOW is tested. Positive cultures are serologically confirmed. The test is performed on Triple Sugar Iron Agar and lasts 4-6 hrs. Phage negative cultures which are lactose- and sucrose negative are tested for lysine decarboxylase and, if Shigella is possible (i.e. in human material on primary plates), for indol production and motility in a semisolid tryptophane agar. Of 22880 Salmonella straine 21977, i.e. 96.1% were phage-sensitive. Strains belonging to certain O-groups (OE) or species are lysed at a lower percentage. However, since they are lysine decarboxylase positive they are not lost and can be submitted to a serological examination.
