2016年11月1日 · The prepared LDH achieved 90% at pH 8.50 which is the pH of wastewater and at the same time exhibited durable antimicrobial activities against MRSA, Gram-negative, Gram-positive and fungi. Results have significant implications in the field of bioremediation of water with little cost, simple operation, high productivity and easiness of the ...

2025年3月25日 · In this study, we demonstrate that moderate exercise significantly reduces gut colonization by methicillin-resistant Staphylococcus aureus (MRSA), a clinically important MDR pathogen.

2019年10月17日 · LDH is an important enzyme that catalyses the mutual transformation of pyruvate and lactic acid. It is essential for MRSA to maintain virulence, evade the innate immunity of the host, and form biofilm (Ferreira et al. 2013). LDH assay showed that oridonin could reduce the synthesis of LDH.

2024年2月15日 · In this study, after treatment with 62.5 µg/mL of CA, the MRSA suspension exhibited significantly higher LDH activity compared to the control group, with a noticeable increase in extracellular LDH activity observed between 4 and 12 h.

据报道，用硝酸盐作为层间阴离子可轻松而简单地获得Zn-Fe层状双氢氧化物（LDH）。 共沉淀法产生高结晶度的LDH，其特征在于XRD，SEM，TEM和FT-IR。 结果表明，在pH 11和4 h时，去除了99.8％的Cd + 2。

These LDH-NPs showed significantly improved killing of intracellular MRSA in HEK 293 cells in vitro. Complete eradication of MRSA was found when cells were treated with LDH-NPs, whereas millions of bacteria remained when treated with vancomycin alone.

2024年11月6日 · Antimicrobial activity as MIC (µg mL −1) of CaO, ZnFe-LDH, and CaO/ZnFe-LDH against methicillin-resistant Staphylococcus aureus (MRSA) and Escherichia coli Compounds Gram (+) bacteria MRSA

2019年11月4日 · The antibacterial activity of LDH-NPs against methicillin-resistance Staphylococcus aureus (MRSA) showed 8-fold lower MICs at pH 6.0 and 7.4, compared to treatment with VCM only. A bacterial cell viability study showed LDH-NPs had an 84.19% killing of MRSA, compared to VCM (49.26%) at the same MIC, further confirming its efficacy.

Objective: We evaluated oridonin effects on MRSA cell membrane and wall, protein metabolism, lactate dehydrogenase (LDH), DNA and microscopic structure. Materials and methods: Broth microdilution and flat colony counting methods were used to measure oridonin minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC ...

2019年10月17日 · In the present study, we evaluated the underlying mechanism of action of oridonin against MRSA by studying its inhibitory effects on cell membrane, cell wall, protein metabolism, lactate dehydrogenase (LDH), DNA and microscopic structure.
