    Title translation Surgical therapy and pathogen detection in endogenous endophthalmitis : Analysis of data from five German eye hospitals.
    Abstract Background: Endogenous endophthalmitis results from hematogenous spread of bacterial or fungal infection in severely diseased patients. Specific systemic and intraocular therapy is required. The basis for this treatment is causal pathogen detection in blood culture or vitreous sample. However, functional results are limited.
    Objective: The current article provides practical hints for surgical therapy and pathogen detection in patients with endogenous endophthalmitis.
    Methods: A retrospective analysis of anonymous data of 68 male and female patients from 2018-2023 from five ophthalmology clinics in Germany was performed.
    Results: Mean age of affected patients was 71.4 years (31-96 years). Surgical therapy included pars plana vitrectomy (ppV) and intravitreal injection (IVOM). In 44 of 68 patients (65%), 1-3 surgeries were performed, 4-6 surgeries were required in 14/68 (21%) of patients, and 10 or more surgeries were required in 4/68 patients (6%). Pathogen detection was possible in 34% of vitreous specimens and in 11% of anterior chamber samples. Mean initial visual acuity was logMAR 1.5. After treatment and a mean follow-up of 2.5 months, mean visual acuity was logMAR 1.3. Preanalytical methods for specimen collection like the Freiburg endophthalmitis set to optimize pathogen detection are presented.
    Conclusion: Severe inflammatory intraocular reactions in endogenous endophthalmitis necessitate a combination of ppV and repeated IVOM. In addition to providing a vitreous sample, ppV also serves to remove inflammatory fibrin membranes. Early pars plana vitrectomy with specific antibiotic or antifungal therapy should be sought in addition to the focus search and systemic therapy.

    Abstract Neurogenic regions of mammalian brain produce many more neurons that will eventually survive and reach a mature stage. Developmental cell death affects both embryonically produced immature neurons and those immature neurons that are generated in regions of adult neurogenesis. Removal of substantial numbers of neurons that are not yet completely integrated into the local circuits helps to ensure that maturation and homeostatic function of neuronal networks in the brain proceed correctly. External signals from brain microenvironment together with intrinsic signaling pathways determine whether a particular neuron will die. To accommodate this signaling, immature neurons in the brain express a number of transmembrane factors as well as intracellular signaling molecules that will regulate the cell survival/death decision, and many of these factors cease being expressed upon neuronal maturation. Furthermore, pro-survival factors and intracellular responses depend on the type of neuron and region of the brain. Thus, in addition to some common neuronal pro-survival signaling, different types of neurons possess a variety of 'neuron type-specific' pro-survival constituents that might help them to adapt for survival in a certain brain region. This review focuses on how immature neurons survive during normal and impaired brain development, both in the embryonic/neonatal brain and in brain regions associated with adult neurogenesis, and emphasizes neuron type-specific mechanisms that help to survive for various types of immature neurons. Importantly, we mainly focus on in vivo data to describe neuronal survival specifically in the brain, without extrapolating data obtained in the PNS or spinal cord, and thus emphasize the influence of the complex brain environment on neuronal survival during development.

    Abstract Review of: Paul van den Akker, Looking for Lines. Theories on the Essence of Art and the Problem of Mannerism, Amsterdam: Amsterdam University Press 2010. The problem of the categorical definition of the nature of art was often regarded as the central challenge of art history. Paul van den Akker examines the history of this problem from the eighteenth century to the 1960s. Thus his book addresses ‘the essence of art history’. In order to do so, he uses the extremely contradictory discussions of ‘Mannerism’ and the use of the line in mannerist art as a relevant case study, and this is supplemented with extensive excursuses on historic concepts of ‘classical art’, of Renaissance painting, of medieval art, or connoisseurship. Johann Joachim Winckelmann, Heinrich Wölfflin, Alois Riegl and John Shearman play key roles in van den Akker’s book. The review mainly asks for the specificity of the analytical categories and the changing role of the visual material used by the antiquarians and early art historians from the later seventeenth to the early twentieth centuries to illustrate and accompany their texts and arguments.

    Abstract Normal breast luminal epithelial progenitors have been implicated as cell of origin in basal-like breast cancer, but their anatomical localization remains understudied. Here, we combine collection under the microscope of organoids from reduction mammoplasties and single-cell mRNA sequencing (scRNA-seq) of FACS-sorted luminal epithelial cells with multicolor imaging to profile ducts and terminal duct lobular units (TDLUs) and compare them with breast cancer subtypes. Unsupervised clustering reveals eleven distinct clusters and a differentiation trajectory starting with keratin 15

    Abstract The ability to capture alterations in the genome or transcriptome by next-generation sequencing has provided critical insight into molecular changes and programs underlying cancer biology. With the rapid technological development in single-cell sequencing, it has become possible to study individual cells at the transcriptional, genetic, epigenetic, and protein level. Using single-cell analysis, an increased resolution of fundamental processes underlying cancer development is obtained, providing comprehensive insights otherwise lost by sequencing of entire (bulk) samples, in which molecular signatures of individual cells are averaged across the entire cell population. Here, we provide a concise overview on the application of single-cell analysis of different modalities within cancer research by highlighting key articles of their respective fields. We furthermore examine the potential of existing technologies to meet clinical diagnostic needs and discuss current challenges associated with this translation.

    Abstract Fast pyrolysis bio-oil requires upgrading in order to be used as an intermediate refinery stream as it contains various acids, oxygenates, heavy compounds and water. This work examines the potential of integrating the organic phase (called BioMates) of a hydrotreated pyrolysis bio-oil as a reliable intermediate refinery stream to be co-processed with a light cycle oil (LCO) towards the production of hybrid fuels. Three blends of BioMates with LCO were fed in a hydroprocessing pilot plant (10/90, 20/80 and 30/70 v/v BioMates/LCO). The dedicated tests aimed to study the BioMates effect on the LCO hydrodesulphurization performance, hydrogen consumption, product quality and catalyst life. The results have confirmed that over 85% per weight of the final product is between 60 and 360 °C boiling range and exhibit favorable fuel properties. The technology can process up to 30% per volume BioMates in LCO without any significant technical limitation, while reducing the hydrogen consumption up to 8.9%. Finally, based on the findings, no clogging or permanent loss of catalyst effectiveness was observed after 37 days on stream.
