Abstract Background Addressing microbial resistance urgently calls for alternative treatment options. This study investigates the impact of a bimetallic formulation containing colistin, silver, and copper oxide on pandrug-resistant, highly virulent Pseudomonas aeruginosa (P. aeruginosa) isolate from cancer patient at National Cancer Institute, Cairo University, Egypt. Methods Silver nanoparticles (Ag NPs), (CuO silver-copper (Ag-CuO NPs) were synthesized using gamma rays, combined with colistin (Col), characterized by various analytical methods. The antimicrobial activity Col-Ag NPs, Col-CuO Col-Ag-CuO NPs against P. was evaluated agar well diffusion method, their minimum inhibitory concentration (MIC) determined broth microdilution. Virulence factors such as pyocyanin production, swarming motility, biofilm formation assessed before after NPs. in vivo efficacy Galleria mellonella model, antibacterial mechanism examined through membrane leakage assay.

The novelty of this study lies in demonstrating a new approach to control wilt diseases using Jania ethyl acetate extract. In the current investigation, potential impacts sp. extract (JE) on Tomato Fusarium oxysporum (FOW) have been studied. vitro antifungal JE against F. (FO) was examined. GC-MS investigation revealed that, compounds possessing fungicidal action were Phenol,2-methoxy-4-(2-propenyl)-,acetate, Eugenol, Caryophyllene oxide, Isoespintanol, Cadinene, Caryophylla-4(12),8(13)-dien-5à-ol and Copaen. exhibited strong FO, achieving 20 mmzone inhibition. experiment, two different methods applied: soil irrigation (SI) foliar application (FS) JE. results showed that both treatments reduced disease index present DIP by 20.83% 33.33% respectively. findings indicated during FOW, proline, phenolics, antioxidant enzymes activity increased, while growth photosynthetic pigments decreased. morphological features, pigments, total phenol content, enzyme infected plants improved when applied through or methods. It is interesting note had substantially less negative effect isozymes peroxidase polyphenol oxidase tomato plants, compared FOW. These reactions differed depending whether foliarly via soil. Finally, use could be utilized commercially as an ecologically acceptable method protect

Cancer and microbial infections place a significant burden on the world's health systems can increase rate of disease mortality. In current study, novel nanocomposite based Gum Arabic, silver copper oxide nanoparticles (GA@Ag-CuO nanocomposite) was synthesized to overcome problem infection in cancer treatment. Characterization using UV-Vis. spectrophotometer reveals that, observed peak spectrum formed by O.D. at 0.755, confirmed that produced GA@Ag-CuO small discernible 360 nm. The particles' diameters varied from 9.5 nm 49.5 nm, with mean diameter 25.53 ± 1.4 created Arabic filtrate rich active functional groups, provided polydisperse NPs were intended reduce, stabilize, act as capping agents. Based XRD data, crystallized had face-centered (fcc) crystal structure. Biosafety assessed toward Wi 38 normal cell line, where it showed safety tested line IC50 154.2 µg/mL.

Abstract The expanding threat presented by developing pathogenic multidrug-resistant (MDR) bacteria calls for an urgent need research, particularly given the growing concern global public health. Bimetallic nanoparticles (NPs) have potential to be utilized a broad variety of pharmacological and biological applications because their outstanding antibacterial activity at low concentrations continuous phase stability. This is especially true when it comes preventing MDR from invading. Several synthetic methods producing bimetallic NPs range analytical (used characterize them) are covered in this brief communication paper. Additionally, I tried highlight literature review on antimicrobial capabilities several synthesized NPs. final section discussed structure mechanism action against bacteria. Electrostatic interaction, damage cell membranes, change enzymes proteins, oxidative stress production reactive oxygen species (ROS), binding proteins that disturbs electron transport chain homeostasis, signal transduction suppression, genotoxicity some possible associations with phenomenon being studied.
