| 3 | Designing an evidence-based free-flap pathway in head and neck reconstruction显示文摘Background:The use of autologous free-tissue transfer is an increasingly utilized tool in the ladder of reconstructive options to preserve and restore function in patients with head and neck cancer.This article focuses on the evidence surrounding perioperative care that optimizes surgical outcomes and describes one tertiary center's approach to standardized free-flap care.Data Sources:This article examines English literature from PubMed and offers expert opinion on perioperative free-flap care for head and neck oncology.Conclusion:Free-flap reconstruction for head and neck cancer is a process that,while individualized for each patient,is best supported by a comprehensive and standardized care pathway.Surgical optimization begins in the preoperative phase and a thoughtful approach to intraprofessional communication and evidence-based practice is rewarded with improved outcomes. | Michelle Mark Michael Eggerstedt Matthew J.Urban Samer Al-Khudari Ryan Smith Peter Revenaugh | 2022 | World Journal of Otorhinolaryngology-Head and Neck Surgery2022，8，2： | 0 |
| 4 | Selective Pb^(2+) removal and electrochemical regeneration of fresh and recycled FeOOH显示文摘Heavy metal pollution is a key environmental problem.Selectively extracting heavy metals could accomplish water purification and resource recycling simultaneously.Adsorption is a promising approach with a facile process,adaptability for the broad concentration of feed water,and high selectivity.However,the adsorption method faces challenges in synthesizing highperformance sorbents and regenerating adsorbents effectively.FeOOH is an environmentally friendly sorbent with low-cost production on a large scale.Nevertheless,the selectivity behavior and regeneration of FeOOH are seldom studied.Therefore,we investigated the selectivity of FeOOH in a mixed solution of Co^(2+),Ni^(2+),and Pb^(2+)and proposed to enhance the capacity of FeOOH and regenerate it by using external charges.Without charge,the FeOOH electrode shows a Pb^(2+)uptake capacity of 20 mg/g.After applying a voltage of-0.2/+0.8 V,the uptake capacity increases to a maximum of 42 mg/g and the desorption ratio is 70%-80%.In 35 cycles,FeOOH shows a superior selectivity towards Pb^(2+)compared with Co^(2+)and Ni^(2+),with a purity of 97%±3%in the extracts.The high selectivity is attributed to the lower activation energy for Pb^(2+)sorption.The capacity retentions at the 5^(th)and the 35^(th)cycles are ca.80%and ca.50%,respectively,comparable to the chemical regeneration method.With industrially exhausted granular ferric hydroxide as the electrode material,the system exhibits a Pb^(2+)uptake capacity of 37.4 mg/g with high selectivity.Our work demonstrates the feasibility of regenerating FeOOH by charge and provides a new approach for recycling and upcycling FeOOH sorbent. | Lei Wang Lexane Deligniere Samantha Husmann Regina Leiner Carsten Bahr Shengjie Zhang Chaochao Dun Matthew M.Montemore Markus Gallei Jeffrey J.Urban Choonsoo Kim Volker Presser | 2023 | Nano Research2023，16，7： | 0 |
