WebNov 15, 2024 · Mitochondrial quality control is central to the health of cells and is achieved through a process known as mitophagy. During mitophagy, stressed or damaged mitochondria that cannot be rescued by fusion/fission cycling are selectively targeted for degradation via autophagy. Mitophagy is primarily mediated by the PTEN-induced kinase … WebMar 20, 2008 · Some researchers have suggested that another process, called fission cycling, may occur along with the r process and might be an essential part of the complex mechanism of heavy element production. Fission cycling happens when unstable neutron-rich nuclei break into roughly equal fragments that become new seeds for neutron capture.

WebDec 29, 2024 · In this description fission cycling has not been taken into account. But if we consider the r-process for nuclei with Z > 80, then fission should be considered. In that case, the heaviest nucleus fissions and a cyclic flow occurs between this nucleus and its fission fragments in the presence of large neutron abundances. We discuss this more in ...
