Last week, Richard Mrowicki, head of strategy and business planning, claimed that building new nuclear plants on the sites of existing ones would reduce decommissioning costs because the sites of ageing reactors will not have to be returned to greenfield status.
"It has been hypothesized, since these cells are found at sites of age-related pathologies, that they are related to the development of these pathologies," says biologist Jan van Deursen of the Mayo Clinic in Rochester, Minnesota, lead author of the new paper.
Senescent cells increase with age in many mammalian tissues and are found at sites of age-related pathologies [8], [18], [19], [20], [21], [22].
Moreover, they are found at sites of age-related pathology, including degenerative disorders such as osteoarthritis and atherosclerosis [ 14] and hyperproliferative lesions such as benign prostatic hyperplasia [ 16] and melanocytic naevi [ 17].
The overlap of phenotypic protocol across sites consisted of age at scan, sex, IQ, and diagnostic information.
Therefore, CcO may be a specific intramitochondrial site of age-related deterioration in the auditory cortex, and CcO subunit III might be a target in the development of presbycusis.
Together, the authors suggest that synaptic transmission is the primary site of age-dependent decline.
Similar changes have been observed in macroscopically abnormal equine flexor tendon [ 7], another common site of age-associated tendon injury.
For each patient, information on diagnosis, gender, age, site-of-onset and age-at-onset were obtained.
