Depending on curcumin concentration and illumination duration, the reactive oxygen species (ROS) increased rapidly after PDI treatment, resulting in severe cell membrane damage and protein degradation. Meanwhile, the activity of ROS defense enzymes such as superoxide dismutase (SOD), catalase (CAT) and...
Fig. 5.Mechanism of antibacterial activity of erythorbyl fatty acid ester (EFE). In the case of Gram-positive bacteria, the hydrophilic moiety of EFE can interact with a positively charged bacterial membrane after penetrating through a peptidoglycan (PG) layer and disrupt the membrane by three-...
curcumin could elicit a greater inhibition of growth of PC cells than either agent alone, and also sought to determine the molecular mechanism of action... Zhiwei Wang a,Sita Desmoulin a,Sanjeev Banerjee a,... - 《Life Sciences》 被引量: 174发表: 2008年 Curcumin‐free turmeric exhibits ant...
Polyurethane is a kind of synthetic polymer composed of isocyanates, polyols and chain extenders. Due to its excellent mechanical flexibility, biodegradability and physicochemical properties, polyurethane is widely used in biological, medical, food and antifouling fields. With the continuous development of...
Electron microscopy serves as a powerful investigative tool in the exploration of the underlying mechanism of action associated with NADES as antimicrobial agents. The high resolution of scanning electron microscopy (SEM) provides researchers with valuable insight into the nature of interactions between NA...
This paper presents the surface treatment results of titanium, veterinary bone wedges. The functional coating is composed of a porous oxide layer (formed by a plasma electrolytic oxidation process) and a polymer poly(sebacic anhydride) (PSBA) layer loaded with amoxicillin (formed by dip coatings)....
antibiotic uptake56,74,75. However, it is important to clarify whether the bacteriostatic activity of CIPRO is sustained when complexed with SRsC1 or only triggered upon release from the complex. The mechanism of release, which could involve environmental triggers such as pH changes or interactions...
Ciprofloxacin (CIP) is a fluoroquinolone antibiotic with broad antibacterial activity for the treatment of bacterial infections, including respiratory infections, and skin and bone infections [64]. The antibacterial mechanism of CIP is the inhibition of bacterial DNA synthesis and gyrases resulting in ba...
The processing of carbon sources as precursors for the production of eco-friendly sustainable carbon dots (CDs) has attracted attention in the literature d
but the antibiofilm effect of Van-MSNs was not significant. However, Van-MSNs did not affect bacterial attachment to surfaces. Van-loaded MSNs did not show a considerable effect on the lysis and sedimentation of RBC. A low interaction of Van-MSNs was detected with albumin (66.5 kDa). The ...
