微纳米气泡技术的研究进展及其在果蔬采后的应用

微纳米气泡（micro-nano-bubbles，MNBs）技术具有比表面积大、气体溶解能力强、表面带有Zeta 电位等特性，在环境治理、清洗、生物医学及农业等领域具有较强研究意义和应用前景。微纳米气泡技术与臭氧（O₃）、二氧化碳（CO₂）、1- 甲基环丙烯（1-MCP）等气体结合可用于果蔬采后非化学洗涤与保鲜，其中臭氧微纳米气泡、二氧化碳微纳米气泡处理通过减少有害微生物数量达到保鲜目的，1-MCP 微纳米气泡通过抑制乙烯生成延长果蔬保鲜期。本文综述了微纳米气泡技术的研究进展及其在果蔬采后的应用，以期为后续推广应用提供理论依据。

Recurrent Temporary Paralysis Reported After Human Rabies Post‐Exposure Prophylaxis

Adverse events can occur after rabies post‐exposure prophylaxis (PEP), and linkage to causality is often difficult to determine. We report a case of recurrent temporary paralysis that began immediately after the initiation of rabies PEP in a man exposed to a bat. The recurrent temporary paralysis first occurred in the patient after his initial dose and then again after day 3 of his rabies PEP. The PEP was terminated prior to a serologic response. The patient continued to experience numerous discrete episodes of temporary paralysis for over two years.     

Ethylene control in cut flowers: Classical and innovative approaches

Ethylene-mediated premature floral senescence and petal or flower abscission affect postharvest longevity of several species used as cut flowers. Exposure to exogenous or endogenously produced ethylene can be controlled in several ways. These include the use of ethylene biosynthesis inhibitors or ethylene action inhibitors, and ethylene removal technologies. In addition, genetic modification can be very effective in controlling ethylene synthesis and perception. We review here the potential for applications of nanotechnology to control ethylene levels and postharvest management in the flower industry. Already, nanosponges have been shown to enhance efficacy of the ethylene inhibitor 1-MCP in several flower species. In carnation, 1-MCP included in nanosponges also allowed better control of Botrytis cinerea damage. However other applications are also considered based on successes in the use of this technology to increase agricultural production and decrease postharvest waste. Nano-metal based sensors could be used for detection of ethylene in the store and to label the product along the distribution chain. Furthermore, nanocomposites could be included as scavengers for ethylene removal in active packaging, and nanocatalysts could promote ethylene catalytic degradation in the warehouse. Nanoparticles could also be introduced into a new generation of packaging to control effects of gases and UV, and increase strength, quality and packaging appearance. This review highlights recent results on the use of nanotechnology sensu lato and potential application for cut flower vase life improvement, focusing on ethylene control strategies.
