Selective Isolation, Identification and Biological Activity Investigation of Rare Actinomycetes from Rhizosphere Soil [PDF]
, 2016 天然产物是新药制备的重要原料，绝大多数来源于微生物的天然产物都分离自放线菌，尤其是链霉菌。链霉菌是放线菌的重要组成成员，能合成结构类型丰富、生物活性多样的次级代谢产物，可用于创制抗生素、抗肿瘤药物、免疫抑制药物、抗虫药物等，在医疗、农业、食品等领域具有重要的应用价值。然而，随着对链霉菌持续的开发利用，目前从链霉菌中发现新型、高活性的次级代谢产物的几率在不断下降，来源于链霉菌的新药研发速度明显放缓。为了解决链霉菌活性次级代谢产物资源日趋枯竭的问题 ...

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Managing diabetic wounds requires simultaneously addressing their infectious, oxidative, and regenerative impairments. To address this, this study integrates a piezoelectric BiOCl@CuSe heterojunction (PFM‐verified) into an injectable F127/HA hydrogel, creating an ultrasound‐responsive smart dressing.

Shuitu Baochi Xuebao, 2003 通过研究比较不同植被类型下土壤中微生物区系、土壤酶活性和土壤生化作用强度,分析了贵州高原喀斯特环境退化演变过程中土壤质量的生物学特性变化过程。结果表明:随喀斯特环境退化程度加剧,土壤微生物总数下降,各主要生理类群数量呈下降趋势,土壤酶活性减弱,土壤生化作用强度降低,对环境反应敏感,可作为反映土壤质量的生物学指标。土壤微生物和酶活性是表征喀斯特环境退化演替过程中土壤质量的重要特征之一。

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Metal‐doped carbon‐based nanomaterials (M‐CNM) play a strategically significant role in next‐generation precision antibacterial and antitumor therapies, as they integrate synergistic photothermal ablation, catalytic reactive oxygen species (ROS) generation, and multimodal imaging capabilities. However, their clinical translation is hindered by

Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT With the growing severity of volatile organic compounds (VOCs) pollution, metal‐organic frameworks (MOFs)‐derived materials offer a promising solution through efficient photothermal catalysis. In this paper, M‐MnOx (M = Cu, Ni, Co, Fe) catalysts derived from manganese‐based MOFs were successfully prepared by the sacrificial template method and

Functional Ecology, Volume 40, Issue 5, Page 1151-1164, May 2026.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant phenology is crucial for understanding plant growth and climate feedback. It affects canopy structure, surface albedo, and carbon and water fluxes. While the influence of environmental factors on phenology is well‐documented, the role of plant intrinsic factors ...
