The involvement of platelets in these processes is often mediated through a variety of platelet-derived chemokines which are released upon activation and act as paracrine and autocrine factors. In this study we investigate CXCL14, a newly described platelet chemokine and its role in thrombus formation as well as monocyte and platelet migration. Additionally, we examine the chemokine receptor CXCR4 as a possible receptor for CXCL14 on platelets. Furthermore, with the use of artificially generated platelets derived from induced pluripotent stem cells (iPSC), we investigate the importance of CXCR4 for CXCL14 mediated platelet functions. METHODS AND RESULTS In this study, we showed that CXCL14 deficient platelets reveal reduced thrombus formation under flow compared to wildtype platelets using a standardized flow chamber. Addition of recombinant CXCL14 normaliia. Further, the described experimental approach using genetically modified human platelets by iPS-CRISPR/Cas9 technology will be helpful for understanding platelet biology.

LncRNA has been implicated in cancer development. The dysregulation of lncRNA myocardial infarction associated transcript (MIAT) has been reported in several cancers while its role in cervical cancer is not described yet. In the current study, the role of MIAT in cervical cancer was explored. We evaluated the expression of MIAT in cervical cancer tissues and cell lines. Furthermore, we explored the effects of MIAT on proliferation and invasion of cervical cancer using cell model and animal transplantation model. We also evaluated the effects of MIAT on activation of PI3K/AKT/mTOR signaling pathway. Our results show that MIAT was up-regulated in cervical cancer tissues and cell lines. Knocking down MIAT resulted in decreased cell proliferation, migration and invasion of cervical cancer cells, as well as suppression of tumor growth in mice. Mechanically, knocking down MIAT suppressed the activation of PI3K/AKT signaling pathway. In conclusion, MIAT promotes cell proliferation and invasion in cervical cancer. © The Author(s) 2020.

To understand the determinants of ARO colonization on NF admission we applied whole-genome sequencing to track the spread of four ARO species across regional NFs and evaluated patient-level characteristics and transfer acute-care hospitals (ACHs) as risk factors for colonization. METHODS 584 patients from six NFs were surveyed for methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecalis/faecium (VREfc/VREfm) and ciprofloxacin-resistant Escherichia coli (CipREc) colonization. Genomic analysis was performed to quantify ARO spread between NFs and compared to patient-transfer networks. The association between admission colonization and patient-level variables and recent ACH exposures was examined using multivariable regression models. RESULTS The majority of ARO isolates across study sites belonged to major healthcare-associated lineages MRSA (ST5;N=89/117); VREfc (ST6;N=68/75); CipREc (ST131;N=58/64), and VREfm (clade A;N=129/129). While the genomic similarity of strains between NF pairs was associated with overlap in their feeder ACHs (Spearman's rho=0.44-0.75, p2 for MRSA and VREfm). Transfer from specific ACHs was an independent risk factor for only one ARO/ACH pair (VREfm/ACH19, aOR=2.48[1.06-5.83]). CONCLUSION In this region, healthcare-associated ARO lineages are endemic among connected NFs and ACHs, making patient characteristics more informative of NF admission colonization risk than exposure to specific ACHs. © The Author(s) 2020.

In this study, we investigate clinical and laboratory features and short-term outcomes of patients with Corona Virus Disease 2019(COVID-19). METHODS All patients with COVID-19 admitted to Wuhan University Zhongnan Hospital in Wuhan, China, between January 3 and February 1, 2020 were included. All those patients were with laboratory-confirmed infection. Epidemiological, clinical, radiological characteristics, underlying diseases, laboratory tests treatment, complications and outcomes data were collected. Outcomes were followed up at discharge until Feb 15, 2020. RESULTS The study cohort included 102 adult patients. The median (IQR) age was 54 years (37-67years) and 48.0% were female. A total of 34 patients (33.3%) were exposed to source of transmission in the hospital setting (as health care workers, patients, or visitors) and 10 patients (9.8%) had a familial cluster. Eighteen patients (17.6%) were admittransmission, including familial clustering of cases, and nosocomial transmission. There were no differences in mortality among those who did or did not receive antimicrobial or glucocorticoid drug treatment. © The Author(s) 2020.

However, training accurate, widely deployable Deep Learning algorithms requires a plethora of annotated (ground truth) data. Image collections must contain not only thousands of images to provide sufficient example objects (i.e. cells), but also contain an adequate degree of image heterogeneity. RESULTS We present a new dataset, EVICAN - Expert visual cell annotation, comprising partially annotated grayscale images of 30 different cell lines from multiple microscopes, contrast mechanisms, and magnifications that is readily usable as training data for computer vision applications. With 4600 images and ~ 26,000 segmented cells, our collection offers an unparalleled heterogeneous training dataset for cell biology deep learning application development. AVAILABILITY The dataset is freely available (https//edmond.mpdl.mpg.de/imeji/collection/l45s16atmi6Aa4sI?q=). Using a Mask R-CNN imple-mentation, we demonstrate automated segmentation of cells and nuclei from brightfield images with a mean average precision of 61.6 % at a Jaccard Index above 0.5. link2 SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online. © The Author(s) 2020. Published by Oxford University Press.On December 31, 2019 a pneumonia outbreak caused by a new coronavirus (SARS-CoV-2) was detected in the city of Wuhan (China). Due to the high capacity of diffusion and human infection it has become a new zoonotic pandemic. The absence of a vaccine has determined the search for antiviral drugs with the capacity to inhibit the replication of the new virus. Among them, remdesivir, an analogue of adenosine, is what seems to have a more promising future. This drug has shown in vitro and in animals a high capacity to block infection and viral replication with attainable concentrations in human plasma. Although all studies have been carried out with SARS-CoV and MERS-CoV, it seems that by virological and functional analogy, remdesivir is one of the few antiviral drugs with proven efficacy. However, studies and clinical trials in humans are required to know the result of their application in them. link3 ©The Author 2020. Published by Sociedad Española de Quimioterapia.

A recent study [J. Mater. Chem. C, 2019, 7, 9756] reported a stable surface structure with one B atom per carbon atom based on high-symmetry adsorption sites having a negative electron affinity (EA) property. In this work, using the global structure prediction method and first-principle calculations, four kinds of B-diamond (100) surfaces with 0.5 monolayers (0.5 ML, one B atom per two carbon atoms), and 1 ML-α, 1 ML-β, and 1 ML-γ (one B atom per carbon atom with three types of configurations known as α, β, and γ) coverages obtained are dynamically and thermally stable. The calculations reveal that B termination effectively modulates the EA of the diamond (100) surface. The 0.5 ML coverage has a small positive EA of 0.24 eV, while the latter three 1 ML coverages with different configurations possess the negative EA of -1.27, -1.25, and -0.76 eV, respectively, due to the difference in charge accumulation and surface dipole moment. Moreover, the B-related surface states are introduced into the bandgap of the bulk diamond, and the band dispersions of the surface states are small (large) in 0.5 ML and 1 ML-γ (1 ML-α and 1 ML-β) as a consequence of the different arrangements of B atoms and the bond lengths between B atoms on the surface. Our finding provides theoretical guidance for the design and fabrication of B-diamond-based electronic devices.The actin cytoskeleton is crucial for endocytosis, intracellular trafficking, cell shape maintenance and a wide range of other cellular functions. Recently introduced cell-permeable fluorescent actin probes, such as SiR-actin, suffer from poor membrane permeability and stain some cell populations inhomogeneously due to the active efflux by the plasma membrane pumps. We analyzed a series of new probes composed of jasplakinolide and modified rhodamine fluorophores and found that rhodamine positional isomerism has a profound effect on probe performance. The probes based on the 6'-carboxy-carbopyronine scaffold are considerably less susceptible to efflux and allow efficient staining without efflux pump inhibitors. They can be used for 2D and 3D fluorescence nanoscopy at high nanomolar concentrations without significant cytotoxicity. We show that jasplakinolide-based fluorescent probes bind not only to actin filaments, but also to G-actin, which enables imaging highly dynamic actin structures. We demonstrate an excellent performance of the new probes in multiple organisms and cell types human cell lines, frog erythrocytes, fruit fly tissues and primary neurons.
