    Therapeutic ROS and Immunity in Cancer-The TRIC-21 Meeting
    (Basel : MDPI, 2021) Bekeschus, Sander; Emmert, Steffen; Clemen, Ramona; Boeckmann, Lars
    The first Therapeutic ROS and Immunity in Cancer (TRIC) meeting was organized by the excellence research center ZIK plasmatis (with its previous Frontiers in Redox Biochemistry and Medicine (FiRBaM) and Young Professionals' Workshop in Plasma Medicine (YPWPM) workshop series in Northern Germany) and the excellence research program ONKOTHER-H (Rostock/Greifswald, Germany). The meeting showcased cutting-edge research and liberated discussions on the application of therapeutic ROS and immunology in cancer treatment, primarily focusing on gas plasma technology. The 2-day hybrid meeting took place in Greifswald and online from 15-16 July 2021, facilitating a wide range of participants totaling 66 scientists from 12 countries and 5 continents. The meeting aimed at bringing together researchers from a variety of disciplines, including chemists, biochemists, biologists, engineers, immunologists, physicists, and physicians for interdisciplinary discussions on using therapeutic ROS and medical gas plasma technology in cancer therapy with the four main sessions: "Plasma, Cancer, Immunity", "Plasma combination therapies", "Plasma risk assessment and patients studies", and "Plasma mechanisms and treated liquids in cancer". This conference report outlines the abstracts of attending scientists submitted to this meeting.

    Medical gas plasma-stimulated wound healing: Evidence and mechanisms
    (Amsterdam [u.a.] : Elsevier, 2021) Bekeschus, Sander; von Woedtke, Thomas; Emmert, Steffen; Schmidt, Anke
    Defective wound healing poses a significant burden on patients and healthcare systems. In recent years, a novel reactive oxygen and nitrogen species (ROS/RNS) based therapy has received considerable attention among dermatologists for targeting chronic wounds. The multifaceted ROS/RNS are generated using gas plasma technology, a partially ionized gas operated at body temperature. This review integrates preclinical and clinical evidence into a set of working hypotheses mainly based on redox processes aiding in elucidating the mechanisms of action and optimizing gas plasmas for therapeutic purposes. These hypotheses include increased wound tissue oxygenation and vascularization, amplified apoptosis of senescent cells, redox signaling, and augmented microbial inactivation. Instead of a dominant role of a single effector, it is proposed that all mechanisms act in concert in gas plasma-stimulated healing, rationalizing the use of this technology in therapy-resistant wounds. Finally, addressable current challenges and future concepts are outlined, which may further promote the clinical utilization, efficacy, and safety of gas plasma technology in wound care in the future.
