Photosensitizing Activity of Pegylated Pheophorbide a
, 2010 Photodynamic therapy (PDT) is a non-invasive therapeutic modality used in a various number of diseases and cancer. It involves the systemic or topic administration of a photosensitizer, followed by irradiation with light. The activated photosensitizer converts oxygen to singlet oxygen and/or reactive oxygen species (ROS) which lead to cell death and ...

Quantitative Analyses of Programmed Cell Death (PCD) Relevant Indicators in Postharvest Vegetable
Future Postharvest and Food, Volume 2, Issue 4, Page 444-457, December 2025.The PCD relevant indicators of postharvest vegetable. ABSTRACT The measurement of factors related to postharvest programmed cell death (PCD) in vegetables is crucial for understanding the physiological and metabolic pathways involved in vegetable ripening, aging, and stress responses. PCD is an actively regulated process orchestrated by the interaction
