When applied to the situation seen in the United States during the 20th century, the authors found that the overall economic gains of increased longevity are enormous.
In the extreme life expectancy version of the compression of morbidity scenario we assume that the additional gain in longevity is the result of a further improvement of health.
As research-led advances in biomedicine are an important source of gains in longevity, investments in research on ageing should properly be seen within the context of their potentially enormous societal returns.
This gain in longevity was diminished by the knockdown of the essential autophagy gene bec-1, the worm ortholog of mammalian beclin-1.
The reflexive association of longevity gains with economic decline bolsters contemporary myths predicting the demise of Social Security.
These type of studies thus ignore the possibility of longevity gains without improvement in underlying health, which would most likely lead to higher health spending.
In this paper, we use scenario analysis to assess how the influence of longevity gains on health expenditure growth is driven by the uncertain relationship between longevity and health.
Knockdown of the C. elegans p53 ortholog cep-1 (which is known to increase the longevity of nematodes by stimulating autophagy) failed to enhance the gain in longevity mediated by sir-2.1 overexpression, in line with the hypothesis that p53 depletion and SIR-2.1 accumulation act through similar pathways to prolong survival.
At a minimum, they should look at the numerous mutations (mostly loss-of-function, but some gain-of-function) that have been reported to extend longevity in yeast.
DAF-28 is thought to activate DAF-2 and so promote normal, reproductive growth and longevity, but sa191 is a dominant negative gain-of-function allele [ 35].
Care of children with spina bifida has significantly advanced in the last half century, resulting in gains in longevity and quality of life for affected children and caregivers.
