These scripts appear to be difficult to adapt appropriately to under-performing trainees. Importantly, supervisor scripts also promote patient entrustment, increasing the likelihood of patients returning to the trainee and training practice for subsequent review, which is a major mechanism for ensuring patient safety in general practice. Theories of entrustment in general practice training must account for the interplay between supervisor, trainee and patient entrustment processes, and work-related constraints. Gaps between entrustment as espoused in theory, and entrustment as enacted, may suggest limitations of entrustment theory when extended to the general practice context, and/or room for improvement in the oversight of trainee consultations in general practice training.Photodynamic therapy (PDT) is gradually becoming an alternative method in the treatment of several diseases. Here, we investigated the role of oxygen in photodynamically treated cervical cancer cells (HeLa). The effect of PDT on HeLa cells was assessed by exposing cultured cells to disulphonated zinc phthalocyanine (ZnPcS2) and tetrasulphonated zinc tetraphenylporphyrin (ZnTPPS4). Fluorescence microscopy revealed their different localizations within the cells. ZnTPPS4 seems to be mostly limited to the cytosol and lysosomes, whereas ZnPcS2 is most likely predominantly attached to membrane structures, including plasmalemma and the mitochondrial membrane. Phototoxicity assays of PDT-treated cells carried out under different partial pressures of oxygen showed dose-dependent responses. Interestingly, ZnPcS2 was also photodynamically effective at a minimal level of oxygen, under a nitrogen atmosphere. On the other hand, hyperbaric oxygenation did not lead to a higher PDT efficiency of either photosensitiz
