Under the optimized conditions, the removal rate reach to 99% of 50 mg/L MB within 60 min irradiation time. Moreover, the MB removal rate was over 90% through six repeated experiments, which proved that the CuSe-PDA/g-C3N4 composite nanomaterials have good stability and reusability.Bisphenol A (BPA) is, due to its widespread use including the production of plastic materials, an ubiquitous pollutant in the aquatic environment. Due to evidence of adverse BPA effects on the environment and human health, its use has been restricted and replaced by analogues such as bisphenol F (BPF). This study examined the toxicity of BPA, BPF and their mixture towards primary producers, the eukaryotic green alga Pseudokirchneriella subcapitata and the prokaryotic cyanobacterium Synechococcus leopoliensis. The results demonstrated that S. leopoliensis is more sensitive than P. subcapitata, whereas toxic potential of the two BPs is comparable and represents comparable hazard for phytoplankton. The toxicity of the binary mixture was predicted by different models (concentration addition, independent action, combination index and the isobologram method) and compared to experimental data. Additive effect was observed in P. subcapitata over the whole effect concentration range (EC5-EC90), whereas in S. leopoliensis, no pronounced combined effect was observed. The environmental risk characterisation based on the comparison of reported concentrations of BPA and BPF in surface waters to the predicted no-effect concentration values obtained in this study showed that at certain industrial areas, BPA represents environmental risk, whereas BPF does not. However, BPF concentrations in aquatic environment are expected to increase in the future. To enable environmental risk assessment of BP analogues, more data on the toxicity to aquatic species, including combined effect, as well as data on their occurrence in the aquatic environment are needed.Graphical abstract.Recently, extensive researches were performed on carbon dioxide (CO2) capture using nano solvents. In this study, three different modified magnetic nanoparticles (NPs), including Fe3O4-Proline (Fe3O4-P), Fe3O4-Lysine (Fe3O4-L), and Fe3O4@SiO2-NH2 NPs were produced to alter and enhance the properties of Fe3O4 NPs for CO2 capture in sulfinol-M as a base solvent. CO2 capture experiments were carried out in a high-pressure batch apparatus in which CO2 absorbed into sulfinol/nano-sulfinol. The influences of NP type, NP loading, and gas phase pressure on CO2 capture were studied. Based on the obtained results, Fe3O4-L and Fe3O4@SiO2-NH2 NPs are notably capable on increasing the CO2 capture capacity of sulfinol-M, and they improved CO2 capture up to 6.3% and 13.36% as compared with the base fluid. Moreover, experiments indicated that all nanosolutions have higher CO2 capture efficiency at higher pressures. Eventually, the effect of NPs stability on CO2 capture was investigated and discussed.The potentially symbiotic mycorrhizal associations dominated by arbuscular mycorrhizal (AM) fungi have become a new topic in bioremediation research in response to global change. Biological soil crusts (biocrusts) play an important role in arid and semi-arid ecosystems. However, AM fungal diversity in the soils underlying moss biocrusts in coal mining subsidence areas remains poorly understood. Here, samples of the soil underlying moss biocrusts in an area inoculated with an AM fungus (AM-BS) and an uninoculated area (CK-BS) plus soil samples from an uninoculated bare area (CK-NBS) were collected from the subsidence area of Shendong Daliuta mine at Yulin, northwest China. CDK inhibitor AM fungal community diversity indices were maximum in AM-BS, intermediate in CK-BS, and minimum in CK-NBS (P available nitrogen (alkali-N). SWC, alkali-N, Olsen-P, and SOM were significantly related to the abundance of Glomus and Claroideoglomus, and TG, EEG, and pH were positively related to Diversisipora. In summary, inoculation with the exotic AM fungus and moss biocrust cover created a eutrophic microhabitat for AM fungi in the soils underlying moss biocrusts in the coal mining subsidence area.A culturally cultivated ignorance with regard to the care and presentation of tightly-curled hair pervades American society. This ignorance masquerades as a discourse of manageability, which supports institutional prohibitions of historically Black American hairstyles. In other words, rather than acknowledging our knowledge deficits, we attribute the medical and aesthetic consequences of our ignorance to the hair itself. The insidious implication is that the display of tightly curled hair is not a matter of taste but indicative of a lack of self-care. I conclude that this trend is racially prejudicial and that laws and education are possible mechanisms of redress.Two pediatric accidents in Jane Austen's Persuasion (1818) and one in Margaret Oliphant's The Doctor's Family (1863) are examined from the point of view of trauma management with analysis of contributing risk factors, medical management, concerns of parents and bystanders, and course of recovery. Risk factors for injury are impulsivity, poor supervision, and parents who are unable to set limits. Medical attention is swift and competent, but no heroic measures are used; the management of the injuries, concussion with loss of consciousness and dislocation of the collar bone, is consistent with the way these conditions are, for the most part, still managed today, and successful recovery depends on careful nursing and rest. Louisa Musgrove, who suffers a severe head injury, requires ten weeks of convalescence and undergoes a marked personality change, which we might today attribute in part to post-concussion syndrome but which may reflect contemporary debate about the biological basis of personality and behavior. A sudden traumatic injury to a child or adolescent changes the narrative abruptly, in fiction or in life, dividing a story into before and after, introducing grief and anxiety, and requiring that plans be rethought and personal relationships reshuffled with decisions about caretaking and nursing.
Quantitative benefit-risk models (qBRm) applied to vaccines are increasingly used by public health authorities and pharmaceutical companies as an important tool to help decision makers with supporting benefit-risk assessment (BRA). However, many publications on vaccine qBRm provide insufficient details on the methodological approaches used. Incomplete and/or inadequate qBRm reporting may affect result interpretation and confidence in BRA, highlighting a need for the development of standard reporting guidance.
Our objective was to provide an operational checklist for improved reporting of vaccine qBRm.
The consolidated standards of reporting quantitative Benefit-RIsk models applied to VACcines (BRIVAC) were designed as a checklist of key information to report in qBRm scientific publications regarding the assessed vaccines, the methodological considerations and the results and their interpretation.
In total, 22 items and accompanying definitions, recommendations, explanations and examples were provided and divided into six main sections corresponding to the classic subdivisions of a scientific publication title and abstract (items 1-2), introduction (items 3-4), methods (items 5-15), results (items 16-17), discussion (items 18-20) and other (items 21-22).
