ABSTRACT Due to their exceptional porosity, structural versatility, and modular coordination chemistry, metal–organic frameworks (MOFs) have emerged as versatile platforms for targeted drug delivery. These structures enable fine‐tuning of pore size, surface activity, and framework stability for the encapsulation of a broad range of therapeutics ...

ABSTRACT The healing of diabetic chronic wounds is hindered by multiple pathological barriers, including oxidative stress imbalance induced by hyperglycemia, persistent bacterial infection, and impaired neovascular function. This study developed an F127–HA–BiOCl@CeO2 (FHBC) hydrogel dressing with acoustic responsiveness, achieving tissue repair through

ABSTRACT Infected bone defects represent a dual therapeutic challenge demanding concurrent infection inhibition and osteogenesis promotion. Systemic antibiotic administration is taken as a classical treatment protocol but often yields inadequate local antibiotic concentrations and delayed bone repair.

Read the free Plain Language Summary for this article on the Journal blog. Abstract Root activity creates unique microbial hotspots in the rhizosphere by influencing the metabolic activities of surrounding soil microorganisms, profoundly regulating the dynamics of soil organic carbon (SOC). However, how root economic strategies affect the formation and

对三江平原3种典型湿地(毛苔草湿地、小叶章湿地、岛状林湿地)的土壤酶活性、土壤养分进行了研究,探讨了不同湿地土壤酶与土壤养分及酶活性间的相关性。结果表明:不同湿地土壤酶活性和土壤养分含量有较大差异。土壤蔗糖酶、脲酶、过氧化氢酶、淀粉酶活性与土壤有机质、全氮、碱解氮含量变化趋势一致,表现为毛苔草湿地>小叶章湿地>岛状林湿地。酸性磷酸酶活性表现为岛状林湿地>毛苔草湿地>小叶章湿地;纤维素酶活性则表现为毛苔草湿地>岛状林湿地>小叶章湿地。经分析,土壤酶活性和养分密切相关,且酶活性间存在一定的相关关系,其中脲酶、

不同种植密度条件下两种穗型冬小麦品种根际土壤酶活性的动态变化
在大田试验条件下,研究了2种穗型冬小麦品种在不同种植密度条件下根际土壤酶活性的动态变化。结果表明,随着生育时期的推进,两种穗型冬小麦品种根际土壤蛋白酶、过氧化氢酶和脲酶活性均呈先增高后降低的单峰曲线变化,拔节期和抽穗期活性较高,返青期和开花期活性则较低。不同种植密度条件下,豫麦49—198系根际土壤蛋白酶、脲酶活性均随密度增加呈先增高后降低的变化趋势,而过氧化氢酶活性表现不明显;兰考矮早八3种根际土壤酶活性随密度增加呈先降低后增高的变化趋势。不同密度水平下3种酶活性的方差分析表明,蛋白酶 ...
