Bacterial resistance to antibiotics is recognized as one of the greatest threats in modern healthcare, taking a staggering toll worldwide. New approaches for controlling bacterial infections must be designed, eventually combining multiple strategies for complimentary therapies. This review explores an old/new paradigm for multi-targeted antibacterial(More)
Nanoghosts derived from mesenchymal stem cells and retaining their unique surface-associated tumor-targeting capabilities were redesigned as a selective and safe universal nonviral gene-therapy platform. pDNA-loaded nanoghosts efficiently targeted and transfected diverse cancer cells, in vitro and in vivo, in subcutaneous and metastatic orthotopic tumor(More)
In previous studies, the oligo-acyl-lysyl (OAK) C12(ω7)K-β12 added to cultures of gram-positive bacteria exerted a bacteriostatic activity that was associated with membrane depolarization, even at high concentrations. Here, we report that multidrug-resistant Staphylococcus aureus strains, unlike other gram-positive species, have reverted to the sensitive(More)
While individually inefficient against Gram-negative bacteria, in-vitro combinations of rifampin and OAK were mutually synergistic since sub-minimal inhibitory concentrations of one compound have potentiated the other by 2-4 orders of magnitude. Synergy persisted in-vivo as single-dose systemic treatment of Klebsiella infected mice resulted in 10-20% versus(More)
Here we describe a new procedure for ascospore isolation from cultures containing a majority of unsporulated vegetative cells of Saccharomyces cerevisiae. The EZ ascospore isolation procedure relies on the combination of two conventional protocols, diethyl ether treatment and modified zymolyase treatment, allowing a significant increase in the efficiency of(More)
To address the need for novel alternatives to antibiotics, we attempted to sensitize gram-negative bacilli to innate antibacterial protagonists. We report a lipopeptide-like sequence (C10OOc12O) that inflicted outer membrane damage at a low micromolar range, whereas measurable bacterial growth inhibition in broth medium required >10-fold higher(More)
