      Apoptosis is a key cell death pathway in mammalian cells. Understanding this process and its regulation has been a subject of study in the last three decades. Members of the Bcl-2 family of proteins are involved in the ...

    • Layer-by-Layer coating of aminocellulose and quorum quenching acylase on silver nanoparticles synergistically eradicate bacteria and their biofilms 

      Asenova Ivanova, Aleksandra; Ivanova, Kristina Dimitrova; Tied, Antje; Heinze, Thomas; Tzanov, Tzanko (2020-04-24)
      Article
      Open Access
      The emergence of antibiotic-resistant bacteria and the failure of the existing antibacterial therapeutics call for development of novel treatment strategies. Furthermore, the formation of bacterial biofilms restricts drug ...

    • A potential lignocellulosic biomass based on banana waste for critical rare earths recovery from aqueous solutions 

      Lapo Calderón, Byron Gonzalo; Bou Serra, Jordi; Hoyo Pérez, Javier; Tzanov, Tzanko; Carrillo, Manuel; Peña, Karina; Sastre Requena, Ana María (2020-04-29)
      Article
      Restricted access - publisher's policy
      Rare earth elements (REE) present multiple applications in technological devices but also drawbacks (scarcity and water contaminant). The current study aims to valorise the banana wastes - banana rachis (BR), banana ...

    • Interaction of silver-lignin nanoparticles with mammalian mimetic membranes 

      Hoyo Pérez, Javier; Ivanova, Kristina Dimitrova; Torrent Burgués, Juan; Tzanov, Tzanko (Frontiers Media SA, 2020-05-08)
      Article
      Open Access
      Silver nanoparticles (AgNPs) have broad spectrum antibacterial activity, but their toxicity to human cells has raised concerns related to their use as disinfectants or coatings of medically relevant surfaces. To address ...

    • Antibiofilm poly(carboxybetaine methacrylate) hydrogels for chronic wounds dressings

      The current study demonstrates the benefits of poly(carboxybetaine methacrylate) hydrogels in chronic wound healing. These hydrogels demonstrate high absorbing capacity upon swelling in salt solutions thus revealing great ...

    • Lipid-lipid interactions of Escherichia coli mimetic inner membrane at human physiological temperature 

      Hoyo Pérez, Javier; Torrent Burgués, Juan; Tzanov, Tzanko (2020-03-26)
      Article
      Open Access
      The current strategies to eradicate bacteria require that the antimicrobial agent either penetrate or disrupt the bacterial membrane. In Escherichia coli (E.coli) as a model of Gram-negative strains, the antimicrobials ...
