The high-value utilization of industrial solid waste using a facile and eco-friendly process is of great interest and significance in reducing environmental pollution and developing a green circular economy. Herein, we propose an amyloid-mediated molecular engineering strategy to transform particulate waste into valuable adsorbents for metal ions. Our method has the advantage of aqueous solution fabrication under mild conditions without the use of high-temperature hydrothermal methods and toxic chemical reagents. Amyloid-mediated molecular engineering manipulates the phase transition of bovine serum albumin(BSA)on particulate waste surfaces, resulting in a remarkable ～3.1 times improvement in the adsorption capacity of fly ash, a typical industrial solid waste for gold ions after modification with the phase-transitioned BSA(PTB). The resultant adsorption ability was 69–1,980 times higher than those of conventional and emerging adsorbent materials such as ion exchange resins, activated carbon(AC), covalent organic frameworks(COFs), and metal-organic frameworks(MOFs). We further demonstrated the application of our PTB-modified materials in the recovery of precious metals from low-grade gold ore and electronic waste leachates. Consequently, this strategy could increase the value of waste materials nearly 27 times. In addition, this method is generally extendable to other conventional industrial adsorbents such as resin, clay, and Al2O3, and enhances their adsorption capabilities at least twofold. Overall, this work provides a simple and green approach for improving the adsorption performance of solid particles, and is expected to develop into a universal strategy for transforming waste particles into high-value-added products.

气候变化背景下极端高温天气对人群健康带来极大挑战。高温健康风险的地理分布不均,因此,进行空间异质性评估对于识别高风险区域和指导空间规划至关重要。该文以步行指数来评估人们在户外活动中遭受高温的可能性,并构建高温健康风险评估体系。以南京市主城区为研究对象,从精细化尺度定量评估高温健康风险的空间分布,精准识别高风险区域及主导风险因子。结果表明:①南京主城区步行指数整体呈“内高外低、多核心”的空间格局,高步行指数区具有较高的高温健康风险。②高温危险性、暴露性、敏感性和适应能力在空间分布上存在明显的异质性。高危险性区域集中于高密度建成区和工业用地,城市中心区域呈“高暴露、高敏感、高适应”特征、外围区域则相反。③高风险区域的主导因子类型在空间上呈圈层性:中心区域以高暴露性为主、过渡区域风险因素为综合,外围区域以低适应能力为主。该研究依据主导风险因子提出韧性提升路径,以期为降低城市高温健康风险提供参考。

轨道交通网络是大型城市人口高效通勤的有力保障,在全球气候变化背景下,沿海城市轨道交通网络受到海平面上升及一系列连锁效应的威胁。该文以深圳市为例对未来不同情景下的轨道交通网络进行复杂网络建模及韧性评估。结果表明:①海平面的不断上升,对轨道交通网络的整体韧性带来显著影响;②当考虑到气候变化的累积效应时,网络韧性下降更加显著;③关键站点的失效对轨道交通网络的影响更大,包括自身失效的影响和造成其他站点间接失效的影响;④沿海存在多处较严重的地表沉降区域,区域内站点受到地表沉降和海平面上升的共同作用。研究以海平面上升作为灾害背景进行轨道交通网络的韧性评估并将地表沉降因素考虑在内,可为沿海城市轨道交通的长期安全发展提供理论参考。

Regulatory T(Treg) cells, a subtype of immunosuppressive CD4^+T cells, are vital for maintaining immune homeostasis in healthy people. Forkhead box protein P3(FOXP3), a member of the forkhead-wingedhelix family, is the pivotal transcriptional factor of Treg cells. The expression, post-translational modifications, and protein complex of FOXP3 present a great impact on the functional stability and immune plasticity of Treg cells in vivo. In particular, the mutation of FOXP3 can result in immune dysregulation,polyendocrinopathy, enteropathy, X-linked(IPEX) syndrome, which is a rare genetic disease mostly diagnosed in early childhood and can soon be fatal. IPEX syndrome is related to several manifestations,including dermatitis, enteropathy, type 1 diabetes, thyroiditis, and so on. Here, we summarize some recent findings on FOXP3 regulation and Treg cell function. We also review the current knowledge about the underlying mechanism of FOXP3 mutant-induced IPEX syndrome and some latest clinical *** last, this review offers a novel insight into the role played by the FOXP3 complex in potential therapeutic applications in IPEX syndrome.
