This critical review discusses different approaches towards protection of photoactive materials based on triplet excited state ensembles against deactivation by molecular oxygen though quenching and photooxidation mechanisms. Passive protection, based on the application of barrier materials for packaging, sealing, or encapsulation of the active substances, which prevent oxygen molecules from penetration and physical contact with excited states and active protection, based on the application of oxygen scavenging species are compared. Efficiencies of different approaches together with examples and prospects of their applications are outlined.

“…From this distinguishing feature results the major function of TNTs, which allows direct transfer of material from one cell to another. TNTs were shown to transfer several types of cargo, such as vesicles derived from various organelles (early endosome, endoplasmic reticulum, Golgi complex, and lysosome) (Kadiu & Gendelman, 2011a, 2011bSmith et al, 2011;Wang et al, 2011), plasma membrane components (Rustom et al, 2004), cytoplasmic molecules, Ca 2+ (Smith et al, 2011;Watkins & Salter, 2005), and mitochondria (Pasquier et al, 2013;Pinto et al, 2020;Sáenz-de-Santa-María et al, 2017;Sartori-Rupp et al, 2019;Vignais et al, 2017). In addition, TNT-like structures can transfer pathogens, e.g., bacteria (Onfelt et al, 2006), HIV particles (Jansens et al, 2020;Sowinski et al, 2011), SARS-CoV-2 particles (Pepe et al, 2022), and proteinaceous agents, such as prions , huntingtin assemblies (Costanzo et al, 2013), alpha-synuclein fibrils (Abounit et al, 2016;Dilsizoglu Senol et al, 2021Vargas et al, 2019), and tau aggregates (Chastagner et al, 2020).…”

Tunneling nanotubes (TNTs) are thin membranous channels providing a direct cytoplasmic connection between remote cells. They are commonly observed in different cell cultures and increasing evidence supports their role in intercellular communication, and pathogen and amyloid protein transfer. However, the study of TNTs presents several pitfalls (e.g., difficulty in preserving such delicate structures, possible confusion with other protrusions, structural and functional heterogeneity, etc.) and therefore requires thoroughly designed approaches. The methods described in this protocol represent a guideline for the characterization of TNTs (or TNT‐like structures) in cell culture. Specifically, optimized protocols to (1) identify TNTs and the cytoskeletal elements present inside them; (2) evaluate TNT frequency in cell culture; (3) unambiguously distinguish them from other cellular connections or protrusions; (4) monitor their formation in living cells; (5) characterize TNTs by a micropatterning approach; and (6) investigate TNT ultrastructure by cryo‐EM are provided. Finally, this article describes how to assess TNT‐mediated cell‐to‐cell transfer of cellular components, which is a fundamental criterion for identifying functional TNTs. © 2023 Wiley Periodicals LLC.Basic Protocol 1: Identification of tunneling nanotubesAlternate Protocol 1: Identifying the cytoskeletal elements present in tunneling nanotubesAlternate Protocol 2: Distinguishing tunneling nanotubes from intercellular bridges formed during cell divisionBasic Protocol 2: Deciphering tunneling nanotube formation and lifetime by live fluorescent microscopyAlternate Protocol 3: Deciphering tunneling nanotube formation using a live‐compatible dyeBasic Protocol 3: Assessing tunneling nanotubes functionality in intercellular transferAlternate Protocol 4: Flow cytometry approach to quantify the rate of vesicle or mitochondria transferSupport Protocol: Controls to support TNT‐mediated transferBasic Protocol 4: Studies of tunneling nanotubes by cell micropatterningBasic Protocol 5: Characterization of the ultrastructure of tunneling nanotubes by cryo‐EM

Social responsibility is one of the competencies that has been gaining strength since the end of the 20th century, as it is considered a commitment of all for the welfare of others and of the planet. The nursing career is made explicit within the professional competences of the future nurse, therefore, the objective of this study is to know the pedagogical practices that promote social responsibility in nursing students at the Autonomous University of Chile. The research is qualitative, descriptive, non-experimental. The population is composed of 17 professionals who teach in the career, intentionally selecting a sample of seven nurses, to whom a semi-structured interview was applied. The results showed that the pedagogical practices to promote social responsibility are clinical case studies, workshops, debates, role-playing, field trips and clinical practice. It is concluded that the most significant are role-playing and working with clinical cases, because it forces students to question themselves, provide solutions and apply theory. Facing different situations that simulate reality allows them to prepare themselves to make decisions and act responsibly in the face of different problems that they will encounter in the world of work.
