Up to now, numerous emerging methods of cancer treatment including chemodynamic therapy, photothermal therapy, photodynamic therapy, sonodynamic therapy, immunotherapy and chemotherapy have rapidly entered a new stage of development. However, the single treatment mode is often constrained by the complex tumor microenvironment. Recently, the nanomaterials and nanomedicine have emerged as promising avenues to overcome the limitation in cancer theranostics. Especially, metal-organic frameworks (MOFs) have gained considerable interests in cancer therapy because of their customizable morphologies, easy functionalization, large specific surface area, and good biocompatibility. Among these MOFs, iron-based MOFs (Fe-MOFs) are particularly promising for cancer treatment due to their properties as nano-photosensitizers, peroxidase-like activity, bioimaging contrast capabilities, and *** their structural regularity and synthetic tunability, Fe-MOFs can be engineered to incorporate organic molecules or other inorganic nanoparticles, thereby creating multifunctional nanoplatforms for single or combined theranostic modes. Herein, the minireview focuses on the recent advancements of the Fe-MOFs-based nanoplatforms for self-enhanced imaging and treatment at tumor sites. Furthermore,the clinical research development of Fe-MOFs-based nanoplatforms is discussed, addressing key challenges and innovations for the future. Our review aims to provide novice researchers with a foundational understanding of advanced cancer theranostic modes and promote their clinical applications through the modification of Fe-MOFs.

Effects of Chlorine-Based Fertilizers on Tomato Growth under Soilless Culture

引用

Phyton-International Journal of Experimental Botany 2025年第1期94卷 243-250页

作者： Fei Li Meili Ding Hui Yuan Siping Wang Bin Liang college of Agriculture and forestry Technology Weifang Vocational CollegeWeifang262737China college of Resources and Environment Qingdao Agricultural UniversityQingdao266109China

This study investigated the effects of chlorine-based fertilizers under varying nitrogen solution concentrations in a soilless culture system. The experiment included four nitrogen solution concentration levels, with nitrogen concentrations of 6 mmol/L (C1), 12 mmol/L (C2), 18 mmol/L (C3), and 24 mmol/L (C4). Each nutrient concentration level was further divided into four chloride ion treatments (R1, R2, R3, and R4), where 100%, 60%, 33%, and 0% of the NH4+ and K+ ions were derived from NH4Cl and KCl, respectively. The length, surface area and volume of root were significantly higher by 25.3%~136.9%, 40.1%~173.1%, 27.9%~178.0%, respectively, in the R4 treatment than in the R1 and R2 treatments at flowering stage. The aboveground biomass and yield in the R4 treatment were significantly higher, by approximately 15.6%~43.5% and 16.6%~28.6%, respectively, than in the R1, R2, and R3 treatments at the picking stage. The C3 and C4 treatments significantly decreased biomass and yield by 31.9%~50.2% and 20.7%~50.5%, respectively, compared to the C1 and C2 treatments at the picking stage. Besides, the higher nutrient solution increased the incidence of blossom-end rot. In conclusion, high concentrations of chloride ions in nutrient solutions, especially when the Cl− concentration exceeded 10 mmol/L, have been shown to inhibit tomato growth in soilless culture systems. Therefore, replacing sulfur-based fertilizers by chlorine-based fertilizers is not recommended for tomato production under the studied conditions.

Pyridyl-based ketones and 1,6-diketones are both attractive and invaluable scaffolds which play pivotal roles in the construction and structural modification of a plethora of synthetically paramount natural products, pharmaceuticals, organic materials and fine chemicals. In this context, we herein demonstrate an unprecedented, robust and generally applicable synthetically strategy to deliver these two crucial ketone frameworks via visible-light-induced ring-opening coupling reactions of cycloalcohols with vinylazaarenes and enones, respectively. A plausible mechanism involves the selective β-C-C bond cleavage of cycloalcohols enabled by proton-coupled electron transfer and ensuing Giese-type addition followed by single electron reduction and protonation. The synthetic methodology exhibits broad substrate scope,excellent functional group compatibility as well as operational simplicity and environmental friendliness.
