violifolia. The downregulation of cysteine-rich kinases and calcium proteins would enhance Se tolerance of C. violifolia is a novel proposition that has not been reported on other Se hyperaccumulators. This study provides us novel insights to understand Se accumulation and tolerance in plants.3-Monochloropropane-1,2-diol (3-MCPD), 2,3-epoxy-1-propanol (glycidol), and their esters are well-known food contaminants mainly formed by the heat processing of certain refined oils and coexist in various kinds of foodstuffs. However, the combined health effect and the underlying mechanism of 3-MCPD and glycidol coexposure are not well-understood. In this study, we investigated the systemic toxicity effects and the nephrotoxicity mechanisms of 3-MCPD and glycidol coexposure with in vitro and in vivo models, and next-generation sequencing (NGS) analysis. It was found that 3-MCPD and glycidol coexposure for 28 days synergistically induced toxicity in the kidney, lung, testis, and heart in C57BL/6 mice. Kidney was the most sensitive organ to coexposure, and the coexposure had a synergistic effect on inflammation and cytotoxicity through activation of the NLRP3 inflammasome, and the induction of necroptosis, and autophagic cell death in NRK-52E cells. Moreover, the NGS results revealed the genes changes associated with nephrotoxicity, inflammation and with the broad toxicity effects induced by 3-MCPD or glycidol alone or in combination, which were consistent with the results of in vitro and in vivo models. In summary, we report for the first time of the comprehensive toxicity effects and the mechanisms caused by 3-MCPD and glycidol coexposure.Due to the blooming development of nanotechnology, the further understanding of nanomaterials-induced toxicity has been demanded. Following their introduction into a biological matrix, the surface of nanoparticles (NPs) is covered by protein layer, namely corona, which imparts a new biological identity to NPs. Here, we showed that fibrinogen (Fg), but not albumin (BSA) or hemoglobin (Hb), decoration on the surface of silica nanoparticles (SiO2 NPs) ameliorate their pro-autophagic activity in non-phagocytic cells. Surprisingly, this effect of Fg was compromised in phagocytic cells. Further mechanistic investigation suggested coronal Fg has dual effects on the tuning of SiO2 NPs-induced autophagic response. First, Fg decoration blocks SiO2 NPs sedimentation through stabilize SiO2 NPs suspension; secondly, Fg coverage inhibits SiO2 NPs' cellular internalization. These findings provided important insights into the understanding of NPs-corona complexes behaviors and indicate future directions for the investigation of corona-mediated biological activities.Charcot Marie Tooth disease (CMT) is a progressive motor and sensory polyneuropathy, it is characterized by a very heterogeneous molecular basis and phenotype. MFN2 and GDAP1 participate in mitochondrial energy metabolism and the rare coinheritance of its pathogenic variants has been associated with a cumulative effect in the observed phenotype. We describe a patient with a severe axonal CMT and inherited heterozygous MFN2 (p.Leu741Val) and GDAP1 (p.Gln163*) variants. In accordance with a possible digenic inheritance, none of the heterozygous carriers in his family were symptomatic or exhibited electrophysiological abnormalities. We also review all of the previously reported patients with coinheritance of variants in these two genes; similar to our patient, all exhibit a predominantly axonal severe CMT phenotype. Our findings expand the genotypic spectrum of CMT and further support that digenic inheritance should be considered for analyzing and counseling CMT patients. Pressure ulcer development is a known indicator of the quality of care. Negative attitudes towards the prevention of pressure ulcers can lead to preventive care with suboptimal quality. There is no valid and reliable instrument in Iran to assess clinicians' attitudes towards pressure u
