Heterogeneity in expected longevities.
We develop a new methodology to compute differences in the expected longevity of individuals of a given cohort who are in different socioeconomic groups at a certain age. We address the two main problems associated with the standard use of life expectancy: (1) that people's socioeconomic characteristics change, and (2) that mortality has decreased over time. Our methodology uncovers substantial...
متن کاملFunctional Cell Types in Taste Buds Have Distinct Longevities
Taste buds are clusters of polarized sensory cells embedded in stratified oral epithelium. In adult mammals, taste buds turn over continuously and are replenished through the birth of new cells in the basal layer of the surrounding non-sensory epithelium. The half-life of cells in mammalian taste buds has been estimated as 8-12 days on average. Yet, earlier studies did not address whether the n...
متن کاملIncreased longevities of post-Paleozoic marine genera after mass extinctions.
Cohorts of marine taxa that originated during recoveries from mass extinctions were commonly more widespread spatially than those originating at other times. Coupled with the recognition of a correlation between the geographic ranges and temporal longevities of marine taxa, this observation predicts that recovery taxa were unusually long-lived geologically. We analyzed this possibility by asses...
متن کاملWhat are the longevities of teeth and oral implants?
OBJECTIVE To analyse tooth loss and to evaluate the longevity of healthy teeth and teeth compromised by diseases and influenced by therapy as well as that of oral implants. MATERIAL AND METHODS On the basis of an electronic and manual search using key words for survival, success, longevity of teeth, longevity of implants, epidemiology, periodontally compromised, endodontically compromised, ri...
متن کاملCommentary: Heterogeneity in meta-analysis should be expected and appropriately quantified.
It is generally accepted that meta-analyses should assess heterogeneity, which may be defined as the presence of variation in true effect sizes underlying the different studies. This assessment might be achieved by performing a statistical test for heterogeneity, by quantifying its magnitude, by quantifying its impact or by a combination of these. Patsopoulos, Evangelou and Ioannidis propose me...
