Furthermore, the excitability-caused increase in the cell count after Pb-CdH treatment (Cd2+ = 112.4 mg/L) was 30% higher than that of the 100 mg/L Cd2+ treatment. These results proved that the addition of Pb2+ in solution significantly weakened the toxicity of Cd2+.Pre-planting testing of seeds and plantlets for the existence of quarantine pathogens is an important phytosanitary measure. The CRISPR-mediated molecular diagnostic methodologies are being developed for pathogens detection, but many challenges remain. Here, we profiled an engineered Crispr/LbCas12a variant (LbCas12a-5M) that has more robust trans-cleavage activity and a wider PAM sequences (TNTN) preference than wild type. We developed a procedure for screening specific sequences of bacterial plant pathogens, and the designed species-specific crRNA displayed no cross-reactions with other bacterial species. Combined with a simple extraction of bacterial DNA, an LbCas12a-5M-based visual detection technique was established and optimized for detecting quarantine pathogens Erwinia amylovora and Acidovorax citrulli with detection limits up to 40 CFU/reaction and a sensitivity consistent with qPCR assay. This protocol was faster and simpler than qPCR, requiring 40 min or less from sample preparation. We further validated the potential application of the method by showing that it can be used for rapid and accurate diagnosis of A. citrulli on seeds of watermelon, with 100% agreement with the results of qPCR assay. The developed method simplifies the detection of pathogens and provides cost-effective countermeasures to quarantine interventions.Single and multilayered Ti3C2TX MXene (referred to as SLM and MLM in this study, respectively) was applied as catalysts in the ultrasonic (US) process to treat selected pharmaceutical compounds including diclofenac and verapamil (VRP). Due to solid surface, elemental composition, and functional groups of Ti3C2TX MXene, the free OH• production was increased by 48.8% for the US treatment with SLM and 59.8% for the US treatment with MLM compared with the US-only treatment. Additionally, adsorption affected the performance during the US treatment in the presence of the catalyst. Thus, the US treatment in the presence of Ti3C2TX MXene had an enhanced performance not only because of increased oxidation but also because of adsorption, particularly between positively charged VRP and negatively charged Ti3C2TX MXene. Moreover, although the degradation of the performance was higher for SLM (85.1%) than for MLM (81.8%), by improving the dispersion and reducing the size via sonication, the US treatment in the presence of MLM showed the highest synergy effect. In other words, the US treatment in the presence of MLM showed higher performance than the simple sum of oxidation and adsorption. These findings confirm that the US treatment in the presence of MLM may be a promising technology to treat various pharmaceuticals as a more degradable, strongly reusable, and less toxic process.Catalytic activation of peroxymonosulfate (PMS) and peroxydisulfate (PDS) (or collectively known as persulfate, PS) using carbocatalyst is increasingly gaining attention as a promising technology for sustainable recalcitrant pollutant removal in water. Single heteroatom doping using either N, S, B or P is widely used to enhance the performance of the carbocatalyst for PS activation. However, the performance enhancement from single heteroatom doping is limited by the type of heteroatom used. To further enhance the performance of the carbocatalyst beyond the limit of single heteroatom doping, multi-heteroatom doping can be conducted. This review aims to provide a state-of-the-art overview on the development of multi-heteroatom-doped carbocatalyst for PS activation. The potential synergistic and antagonistic interactions of various heteroatoms including N and B, N and S, N and P, and N and halogen for PS activation are evaluated. Thereafter, the preparation strategies to develop multi-heteroatom-doped carbocatalyst including one-step and multi-step preparation approaches along with the characterization techniques are discussed. Evidence and summary of the performance of multi-heteroatom-doped carbocatalyst for various recalcitrant pollutants removal via PS activation are also provided. Finally, the prospects of employing multi-heteroatom-doped carbocatalyst including the need to study the correlation between different heteroatom combination, surface moiety type, and amount of dopant with the PS activation mechanism, identifying the best heteroatom combination, improving the durability of the carbocatalyst, evaluating the feasibility for full-scale application, developing low-cost multi-heteroatom-doped carbocatalyst, and assessing the environmental impact are also briefly discussed.Aquaculture wastewater contained large amounts of pathogenic microorganisms, nitrogen (N) and phosphorus (P). In this study, the nutrient recoveries and wastewater disinfection were simultaneously achieved using Mg-coconut shell carbon (Mg-CSC). The composites were prepared by a ball milling method. The hydrogen peroxide (H2O2) was in-situ generated by the dissolved oxygen reduction driven by Mg corrosion on the CSC surface, which inactivated the microorganisms. Besides that, Mg corrosion provided sufficient Mg ions and appropriate pH conditions for struvite formation. The results show that 5.4-log E.coli removal was achieved under different conditions. Improving the Mg/CSC ratio and composite dosage could shorten the time required for disinfection. In addition to H2O2, singlet oxygen played a critical role. Reactive oxygen species destroyed the cellular structure and killed the bacteria. The recoveries of NH4+-Nand P under certain conditions were about 60% and 91%, respectively. An increased composite dosage could improve the recovery ratio of P. Excessive dosages were not beneficial for removing NH4+-N. The characterization result revealed that struvite crystals were the main precipitates on the CSC surface. The Mg-CSC composites also revealed satisfied nutrient recovery and disinfection performances in the real aquaculture wastewater treatment process.Globally distributed earthworms affect compositions of soil compounds, microbial community structures, as well as antibiotic resistance genes (ARGs). Compared to their surroundings, earthworm gut is a simpler environment which could filter out microbes when soil passes through it. However, little is known about how earthworms affect the dissemination of ARGs in soil, and the understanding of the relationship between microbe-microbe interactions and ARGs is still lacking. Here, we designed a microcosm experiment with earthworm addition, and determined bacterial and fungal community compositions based on amplicon sequencing. We also examined mobile genetic elements (MGEs) and ARGs in earthworm gut and soils using high-throughput qPCR. The results showed significant differences of bacterial, fungal and ARG patterns between gut and soil. Earthworms indirectly impacted the patterns of ARGs in soils by affecting bacterial communities and soil properties, which play key roles in the distribution of ARGs and MGEs. The absolute abundances of MGEs in earthworm gut were significantly lower than those in soils, and earthworms reduce the absolute abundance of MGEs in soils. Earthworms changed the microbial co-occurrence patterns, and reduced bacterial connectivity, which were significantly and positively correlated with MGE abundance. These results highlight the importance of earthworm on the distribution and dissemination of ARGs in soils.

Dermabond® is a liquid surgical sealant containing 2-octyl-cyanoacrylate that has been widely used during head and neck surgeries. This study aims to provide a summary of adverse events related to Dermabond® in head and neck procedures as reported in the MAUDE database, and to report a complete overview of all documented adverse events related to Dermabond® use in current literature.
The US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database was queried for reports of adverse events related to Dermabond® use from January 1, 2010, to February 1, 2020. Data were extracted from reports pertaining to head and neck procedures. In addition, literature review was performed from January 1970 to January 2021. Various adverse events related to Dermabond® were included in the study.
We identified 32 adverse events, from which 29 (90.6%) were patient-related events and 3 (9.4%) were operator-related events. Of the patient-related events, contact dermatitis (CD) (20 [69.0%]) was the most common, followed by wound dehiscence (4 [13.8%]). All of the operator-related events were from inadvertent cut injury (3 [100%]). Following the literature review, adverse events of Dermabond® were categorized into CD, wound dehiscence, infection, and cut injury.
Dermabond® demonstrated utility in various surgical procedures including head and neck surgeries but are associated with risks. This study identified adverse events associated with Dermabond®. Further studies are needed to establish the causation of contact dermatitis in certain populations.
