Hybrid Quatsome‐Encapsulated Silver Nanoparticles as Stable Plasmonic Substrates for Surface‐Enhanced Raman Scattering

open access: yesJournal of Raman Spectroscopy, EarlyView.
In this work, silver nanoparticles encapsulated within quatsome membranes have shown to preserve their plasmonic properties for at least 165 days without aggregation. These hybrid nanostructures enable strong SERS enhancement of pyrene and Prodan by confining the molecules within a few nanometers from the silver surface.

Effect of Melittin on Metabolomic Profile and Cytokine Production in PMA-Differentiated THP-1 Cells

open access: yesVaccines, 2018
Melittin, the major active peptide of honeybee venom (BV), has potential for use in adjuvant immunotherapy. The immune system response to different stimuli depends on the secretion of different metabolites from macrophages.

Antimicrobial Cyclic Peptidomimetics

open access: yesMacromolecular Rapid Communications, EarlyView.
Singular macromolecular cationic, amphipathic cyclic peptidomimetics with poly(2‐oxazoline)s‐esque backbone structure that undergo self‐assembly in water to form uniform nanoparticles were developed. The cyclic peptidomimetics, which act on bacterial cell membranes, exhibit hydrophobic‐dependent antimicrobial activity and toxicity.

Ultrastructural observation on sterilization of melittin [PDF]

open access: yesScience China Life Sciences, 2011
ABSTACT: The effects of melittin on growth and bacteriostasis of four pathogens were extensively investigated using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results indicated that the melittin had a marked bacteriostatic effect on the four pathogenic bacteria. Among these, E.

Export of honeybee prepromelittin in Escherichia coli depends on the membrane potential but does not depend on proteins secA and secY [PDF]

open access: yes, 1989
Honeybee prepromelittin (70 amino acid residues), the precursor of an eukaryotic secretory protein, and a hybrid protein between prepromelittin and mouse dihydrofolate reductase (257 amino acid residues) were expressed in Escherichia coli and ...

Survey of probable synergism between melittin and ciprofloxacin, rifampicin, and chloramphenicol against multidrug-resistant Pseudomonas aeruginosa

open access: yesFrontiers in Microbiology
BackgroundThe emergence of multidrug-resistant bacteria and also biofilm-associated infections is a great health concern due to the failure of available antibiotics. This has alerted scientists to developing alternative antibiotics.
