Is the temporoparietal fascial flap an alternative to free flaps for orbitomaxillary reconstruction?
The temporoparietal fascial flap is a viable alternative to free flaps for orbitomaxillary defects when orbital resection is limited, when obturator reconstruction is desired, or when comorbidities preclude microvascular surgery.
Although the anti-fungal activities of macrolide inhibitors of the mitochondrial F0F1-ATP synthase such as oligomycin, ossamycin and cytovaricin are well-documented, their unusual selectivity toward certain cell types is not widely appreciated. The recent discovery of apoptolidin, followed by the demonstration that it is an inhibitor of the mitochondrial F0F1-ATP synthase, highlights the potential relevance of these natural products as small molecules to modulate apoptotic pathways. The mechanistic basis for selective cytotoxicity of mitochondrial ATP synthase inhibitors is discussed.
