OBJECTIVE Workplace violence against nurses is a widespread phenomenon that has been associated with many unfavorable individual and organizational outcomes. The aim of this study was to analyze the relationship between violence and work functioning in a sample of Italian nurses. DESIGN Cross-sectional, with retrospective analysis of exposure. METHODS All nurses from a local hospital were invited to complete a questionnaire assessing violent experiences that occurred in the previous 12 months. The questionnaire also measured job strain (with the Demand-Control-Support questionnaire), organizational justice (with Colquitt's Questionnaire), and work impairment (with the Nurses Work Functioning Questionnaire). The associations were examined with logistic regression analyses. FINDINGS Of the 302 nurses who were invited, 275 (91.1%) agreed to participate. The total work impairment score was significantly higher among the nurses exposed to violence compared with the nonexposed nurses (42.2 ± 27.8 vs. 31.9 ± 31.6, rative measures for violence control (such as alarms, surveillance, staff increase), and measures to reduce occupational stress, which can include wellness courses, spirituality, organizational improvements, and staffing methodologies. © 2020 Sigma Theta Tau International.Nephrotic syndrome is characterized by proteinuria, hypoalbuminemia, and general edema. These symptoms may persist in children who reach ESRD, which is unfavorable for the patient's allograft outcome. In addition, this may hamper early diagnosis of a relapse after transplantation. Surgical bilateral nephrectomy is often considered for that reason, but medical nephrectomy may be a less invasive alternative. In this retrospective single-center case series, we identified all children on dialysis with ESRD due to nephrotic syndrome in which a medical nephrectomy was attempted before kidney transplantation between 2013 and 2018. Outcome was measured by urine output and serum albumin levels. Eight patients with either congenital nephrotic syndrome or focal segmental glomerular sclerosis were included in the study. All patients received an ACE inhibitor as drug of first choice for medical nephrectomy, to which 5 patients responded with oligoanuria and a significant rise in serum albumin, and 3 patients responded insufficiently. In 1 of these 3 patients, diclofenac was added to the ACE inhibitor, with good result. In the other 2 patients, indomethacin was initiated without success, and surgical bilateral nephrectomy was performed. Overall, 6/8 patients had a successful medical nephrectomy and did not need surgical nephrectomy. No recurrence of nephrotic syndrome was found after kidney transplantation in all but one. Medical nephrectomy with ACE inhibitors and/or non-steroidal anti-inflammatory drugs is a safe and non-invasive therapy to minimize proteinuria in children with ESRD due to nephrotic syndrome before kidney transplantation. We suggest that this strategy should be considered as therapy before proceeding with surgical nephrectomy. © 2020 The Authors.

Besides the presence of recalcitrant polymers, the presence of compounds with antimicrobial properties is known to be important to explain wood durability. Based on the advancement in our understanding of fungal detoxification systems, a reverse chemical ecology approach was proposed to explore wood natural durability using fungal glutathione transferases. A set of six glutathione transferases from the white-rot Trametes versicolor were used as targets to test wood extracts from seventeen French Guiana neotropical species. Fluorescent thermal shift assays quantified interactions between fungal glutathione transferases and these extracts. From these data, a model combining this approach and wood density significantly predicts the wood natural durability of the species tested previously using long-term soil bed tests. Overall, our findings confirm that detoxification systems could be used to explore the chemical environment encountered by wood-decaying fungi and also wood natural durability. © 2020 The Authors.

During the last decades, the field of self-assembled ion channels has been continuously developed. Convergent multidimensional self-assembly strategies have been used for the synthesis of unimolecular channels or non-covalent self-organized channels, designed to mimic natural ion channel proteins and for which a rich array of interconverting or adaptive channel conductance states can be observed. In this review, we give an overview on the development of various self-assembled artificial channels in a bottom-up approach, especially their design, self-assembly behaviour, transport activity in lipid bilayer membranes, mechanism of transport and comparison with natural ion channels. Finally, we discuss their applications, the potential challenges facing in this field as well as future development and perspectives. © 2020 WILEY-VCH Verlag GmbH & Co.

To decrease xenogeneic immune responses, we generated tissue engineered swine leucocyte antigen (SLA)-silenced islet cell clusters (ICC). Single-cell suspensions from pancreatic islets were generated by enzymatic digestion of porcine ICCs. Cells were silenced for SLA class I and class II by lentiviral vectors encoding for short hairpin RNAs targeting beta2-microglobulin or class II transactivator, respectively. SLA-silenced ICCs-derived cells were then used to form new ICCs in stirred bioreactors in the presence of collagen VI. SLA class I silencing was designed to reach a level of up to 89% and class II by up to 81% on ICCs-derived cells. Xenogeneic T cell immune responses, NK cell and antibody-mediated cellular-dependent immune responses were significantly decreased in SLA-silenced cells.
