Solitary fibrous tumor/hemangiopericytoma (SFT/HPC) is a mesenchymal tumor originating from various soft tissues and meninges, which carries the NAB2-STAT6 fusion gene. Meningeal/intracranial SFT/HPCs (icSFT/HPC) have a poor clinical outcome with metastatic behavior compared to soft tissue/extracranial SFT/HPCs (exSFT/HPC), but the underlying genetic factors are unclear. Differentially expressed genes (DEGs) were analyzed by NanoString nCounter assay using RNA extracted from formalin-fixed paraffin-embedded (FFPE) tissue samples. Additionally, immunohistochemistry (IHC) was performed on 32 cases of exSFT/HPC, 18 cases of icSFT/HPC, and additional recurrent or metastatic cases to verify the findings. Pathway analysis revealed that the WNT signaling pathway was enriched in exSFT/HPC. Analysis of DEGs showed that expression of WNT5A was lower and that of MMP9 was higher in icSFT/HPC than in exSFT/HPC (p = 0.008 and p = 0.035, respectively). IHC showed that WNT5A and CD34 expression was high in exSFT/HPC (p less then 0.001, both), while that of MMP9 was high in icSFT/HPC (p = 0.001). Expression of CLDN5 in tumoral vessels was locally decreased in icSFT/HPC (p less then 0.001). The results suggested that decreased WNT5A expression, together with increased MMP9 expression, in icSFT/HPC, may affect vascular tightness and prompt tumor cells to metastasize extracranially.Driving environment perception for automated vehicles is typically achieved by the use of automotive remote sensors such as radars and cameras. A vehicular wireless communication system can be viewed as a new type of remote sensor that plays a central role in connected and automated vehicles (CAVs), which are capable of sharing information with each other and also with the surrounding infrastructure. In this paper, we present the design and implementation of driving environment perception based on the fusion of vehicular wireless communications and automotive remote sensors. A track-to-track fusion of high-level sensor data and vehicular wireless communication data was performed to accurately and reliably locate the remote target in the vehicle surroundings and predict the future trajectory. The proposed approach was implemented and evaluated in vehicle tests conducted at a proving ground. The experimental results demonstrate that using vehicular wireless communications in conjunction with the on-board sensors enables improved perception of the surrounding vehicle located at varying longitudinal and lateral distances. The results also indicate that vehicle future trajectory and potential crash involvement can be reliably predicted with the proposed system in different cut-in driving scenarios.Background. learn more Historically, the most important approach to safety management consisted of controlling variability and error in human performance. This assumption was questioned by the changes of the economy and technology, which introduced higher levels of unpredictability and uncertainty. Starting from this consideration, our research aimed to investigate the issue of organizational safety from the dual perspective of individuals and organizations, with the aim of highlighting the weight that both actors have in the co-construction of a safe workplace. Method. A cross-sectional study was performed among workers of a multinational company of the automotive sector, through an online self-report questionnaire. Results. The results highlight the key role of two variables investigated, linked to safety management organizational mindfulness and organizational citizenship behavior for safety. The first seems to be a partial mediator in the relationship between organizational support and affective commitment; the second, instead, seems to be a complete mediator between organizational support and safety ownership, otherwise non directly related. Conclusions. This study confirms the importance of considering both individual and organizational contribute to safety management in organizations, emphasizing the existing link between safety promotion and employee's motivation and their personal involvement.This case report outlines the strategies underpinning the adaptation of professionalism and ethics strand (P&E) teaching for remote delivery on a Pharmacy programme in response to COVID-19 restrictions. In line with national and University guidance, P&E teaching detailed in this report was delivered online in late 2020. Sessions were generally live and recorded, although some content was pre-recorded using video-capture software. All learning activities, recordings and supporting resources are accessible to students on the University's Virtual Learning Environment. This report reflects on the curriculum, pedagogy and content of P&E teaching, with particular emphasis on teaching related to professional identity formation and moral reasoning competencies development. Design, development and delivery of remote online teaching is considered in the context of P&E teaching. Strategies used to plan for adaptation and delivery of interactive online teaching sessions aligned with P&E teaching are described. Key findings support a scholarship of teaching approach when planning for adaptation to remote online teaching. Purposeful consideration of existing curricular, pedagogical and instructional design enables the teacher to identify critical P&E teaching activities potentially compromised by the move to the online environment. Informed integration of available instructional tools to teaching activities follows. The report concludes with recommendations for future research.Retinal degenerative diseases, such as age-related macular degeneration, retinitis pigmentosa, diabetic retinopathy or glaucoma, represent the main causes of a decreased quality of vision or even blindness worldwide. However, despite considerable efforts, the treatment possibilities for these disorders remain very limited. A perspective is offered by cell therapy using mesenchymal stem cells (MSCs). These cells can be obtained from the bone marrow or adipose tissue of a particular patient, expanded in vitro and used as the autologous cells. MSCs possess potent immunoregulatory properties and can inhibit a harmful inflammatory reaction in the diseased retina. By the production of numerous growth and neurotrophic factors, they support the survival and growth of retinal cells. In addition, MSCs can protect retinal cells by antiapoptotic properties and could contribute to the regeneration of the diseased retina by their ability to differentiate into various cell types, including the cells of the retina. All of these properties indicate the potential of MSCs for the therapy of diseased retinas.
