In recent years, much effort has been focused on the development of the photocatalysts with high performance under visible light irradiation. In this paper, three-dimensional porous La-doped SrTiO3 (LST) microspheres were prepared by a modified sol–gel method, in which the agarose gel/SrCO3 microsphere and La2O3 were employed as the template and the La resource, respectively. The as-prepared LST microspheres exhibit a porous structure with a diameter of about 10 µm and a surface pore size of about 100 nm. The La element was doped into the crystal lattice of SrTiO3 by the substitution of La3+ for Sr2+. Therefore, the absorption edge of LST samples shifts toward the visible light region, and their photocatalytic activity for the Cr(VI) reduction is enhanced under visible light. Among all LST samples, LST-0.5 (the La3+ doping content is 0.5 wt-%) exhibited the highest visible-light photocatalytic activity, which can reduce 84% Cr(VI) within 100 min. This LST materials may become a promising photocatalyst for the facile treatment of wastewater containing poisonous heavy metal ions.

• Current intensification trends in the Rio de la Plata need urgent re-direction.
•Integrated crop-livestock systems reconcile food production with ecosystem services.
•Case studies validate recoupling as a sustainable way to ecological intensification.
The Rio de la Plata region comprises central Argentina, Uruguay, and southern Brazil. Modern agriculture developed around 1900 with recent decades being characterized by the advance of cropping areas over native grasslands. Highly specialized agriculture has decoupled crop and livestock production but has succeeded in intensifying yields. However, significant losses of ecosystem services have been reported. Thus, questions have been raised on the sustainability of this pathway. A glance at world regions that have experienced similar trends suggests that an urgent course correction is needed. A major concern has been the lack of diversity in regions with highly specialized agriculture, promoting renewed interest in integrated crop-livestock systems (ICLS), not only because ICLS are more diverse than specialized systems, but also because they are rare examples of reconciliation between agroecosystem intensification and environmental quality. Consequently, this paper discusses alternatives to redesign multifunctional landscapes based on ICLS. Recent data provide evidence that recoupling crop and animal production increases the resilience of nutrient cycling functions and economic indicators to external stressors, enabling these systems to face climate-market uncertainty and reconcile food production with the provision of diverse ecosystem services. Finally, these concepts are exemplified in case studies where this perspective has been successfully applied.

叉头框蛋白P3(FOXP3)是调节性T细胞(Tregs)的一个主要调节因子,调节性T细胞是能抑制抗原特异性免疫反应的T 细胞亚群,在增强宿主耐受性和维持免疫平衡方面发挥着重要作用。众所周知,FOXP3 与多种蛋白质形成复合物,并能通过乙酰化、磷酸化、泛素化和甲基化等各种翻译后修饰(PTM)进行调节。因此,翻译后修饰可改变FOXP3 的稳定性及其调节基因表达的能力,并最终影响调节性T细胞活性。虽然FOXP3 自身并非理想的药物靶点,但脱乙酰酶、乙酰转移酶、激酶和其他可调节FOXP3 的翻译后修饰的酶均为调控FOXP3 和调节性T细胞活性的潜在靶点。但FOXP3 并非这些酶的唯一底物;因此,当使用相关抑制剂时,必须考虑是否存在有害的“FOXP3脱靶”副作用。
