Living healthier for longer: comparative effects of three heart-healthy behaviors on life expectancy with and without cardiovascular disease [PDF]

open access: yes, 2009
Background: Non-smoking, having a normal weight and increased levels of physical activity are perhaps the three key factors for preventing cardiovascular disease (CVD).

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Life Expectancy [PDF]

open access: yes, 2015
The analysis of life expectancy and longevity is one approach to analysing diversity in the population of ancient Egypt. It is, however, important to understand the difficulties in such calculations and in the data from which such calculations are derived. Adult age is difficult to determine either from documentary or biological sources, so average age-

Global Trends in Life Expectancy and Healthy Life Expectancy

open access: yes, 2023
Abstract In the known history of humanity, life expectancy scarcely exceeded 30 years, with half of newborns dying before age five, up to the 18th century. However, from the 18th century onward, major epidemics were combatted more efficiently, famines became less frequent, and life expectancy thus began to increase, first in Northwest

Changing mortality and average cohort life expectancy [PDF]

open access: yes
Period life expectancy varies with changes in mortality, and should not be confused with the life expectancy of those alive during that period. Given past and likely future mortality changes, a recent debate has arisen on the usefulness of the period ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

open access: yesFEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Life expectancy: Lower and upper bounds from surviving fractions and remaining life expectancy

open access: yesDemographic Research, 2011
We give simple upper and lower bounds on life expectancy. In a life-table population, if e(0) is the life expectancy at birth, M is the median length of life, and e(M) is the expected remaining life at age M, then (M+e(M))/2≤e(0)≤M+e ...

One vicinity, two neighbors, and two different stories: a comparison of mortality experiences in Greece and Bulgaria since the 1960s

open access: yesJournal of Balkan Studies
Greece and Bulgaria are neighboring countries. In the 19th century, the two countries became independent after the Greеk-Turkish and Russian-Turkish Wars, respectively.

Epidemics and Forecasts of Life Expectancy

open access: yesGerontology, 2021
In 1997, Vaupel [1] wrote a rather optimistic paper entitled “The average French baby may live 95 or 100 years.” While the author stressed that “environmental collapse, nuclear devastation, etc.” may nevertheless lead the 1996 birth cohort to “short, miserable lives,” he favoured the hypothesis that “if health, economic and social progress accelerate ...
