羧甲基纤维素水凝胶分子内含有大量的羧基和羟基官能团,能够高效吸附水体中的有机污染物,同时由于水凝胶的易回收和生物相容性,目前已被广泛应用于印染废水处理。但传统的羧甲基纤维素水凝胶制备方法存在耗时长、成本高、污染重等问题... 羧甲基纤维素水凝胶分子内含有大量的羧基和羟基官能团,能够高效吸附水体中的有机污染物,同时由于水凝胶的易回收和生物相容性,目前已被广泛应用于印染废水处理。但传统的羧甲基纤维素水凝胶制备方法存在耗时长、成本高、污染重等问题。该实验设计结合我国资源化发展和环境保护需要,以纤维素水凝胶为原料,以水代替部分传统有机溶剂,开发出一种室温下快速制备羧甲基纤维素水凝胶的绿色合成方案。合成时间从44 h缩短至约4h,制备成本降低约95%,同时减少了化学试剂的使用,避免了二次污染。实验选用典型染料亚甲基蓝作为模型污染物,考察了羧甲基纤维素水凝胶对其在不同水体环境中的吸附性能。 展开更多

Magnesium(Mg)-based bioresorbable stents represent a potentially groundbreaking advancement in cardiovascular therapy;offering tem-porary vessel support and complete biodegradability—addressing limitations of traditional stents like in-stent restenosis and long-term com-plications.However,challenges such as rapid corrosion and suboptimal endothelialisation have hindered their clinical adoption.This review highlights the latest breakthroughs in surface modification,alloying,and coating strategies to enhance the mechanical integrity,corrosion resistance,and biocompatibility of Mg-based stents.Key surface engineering techniques,including polymer and bioactive coatings,are ex-amined for their role in promoting endothelial healing and minimising inflammatory responses.Future directions are proposed,focusing on personalised stent designs to optimize efficacy and long-term outcomes,positioning Mg-based stents as a transformative solution in interventional cardiology. 展开更多

Worldwide,a majority of routine endoscopic procedures are performed under some form of sedation to maximize patient comfort.Propofol,benzodiazepines and opioids continue to be widely used.However,in recent years,Remimazolam is gaining immense popularity for procedural sedation in gastrointestinal(GI)endoscopy.It is an ultra-short-acting benzodiazepine sedative which was approved by the Food and Drug Administration in July 2020 for use in procedural sedation.Remimazolam has shown a favorable pharmacokinetic and pharmacodynamic profile in terms of its non-specific metabolism by tissue esterase,volume of distribution,total body clearance,and negligible drug-drug interactions.It also has satisfactory efficacy and has achieved high rates of successful sedation in GI endoscopy.Furthermore,studies have demonstrated that the efficacy of Remimazolam is non-inferior to Propofol,which is currently a gold standard for procedural sedation in most parts of the world.However,the use of Propofol is associated with hemodynamic instability and respiratory depression.In contrast,Remimazolam has lower incidence of these adverse effects intra-procedurally and hence,may provide a safer alternative to Propofol in procedural sedation.In this comprehensive narrative review,highlight the pharmacologic characteristics,efficacy,and safety of Remimazolam for procedural sedation.We also discuss the potential of Remimazolam as a suitable alternative and how it can shape the future of procedural sedation in gastroenterology. 展开更多
