We have earlier demonstrated anti carcinogenic activity of ellagic acid in DL mice in terms of morphologic changes, as well as by increase in longevity, decrease in volume of ascites fluid accumulation in peritoneum and by decrease in cell proliferation with increased survival [ 4].
Longevity decreased with increasing inbreeding level when animals were acclimated to 20°C (C: 37.2 ± 0.98 d = I1: 35.8 ± 0.94 d > I2: 31.0 ± 1.05 d), but tended to increase with increasing inbreeding level when animals were acclimated to 27°C (C: 22.2 ± 1.0 d = I1: 24.4 ± 1.06 d = I2: 26.6 ± 1.13 d; Tukey HSD; significant inbreeding level * adult temperature interaction).
Similarly, switchgrass pollen longevity decreased rapidly under sunny atmospheric conditions, with a half-life of less than 4·9 min and a complete loss of viability in 20 min. Under cloudy atmospheric conditions, the half-life of switchgrass pollen was more than five-fold longer than under sunny conditions, and it took approx. 150 min to lose viability completely (Ge et al., 2011).
Even if let-363 promotes longevity by decreasing protein synthesis, this cannot be the only mechanism of lifespan extension for the TOR pathway, since decreasing translation initiation factor levels by eIF2β or eIF4G RNAi, or by ife-2 mutation, does not extend lifespan in daf-16 mutants and actually shortens that of daf-2 mutants, in contrast to the results of let-363 RNAi) let-363 RNAi
In addition, April 1 snow water equivalent and snowpack longevity also decreased between 1951 1980 and 1981 2010.
Recovery from illness is impaired, cardiovascular reactivity to stress is increased, and longevity is decreased (Nelson, 2016).
With aging population, increase in longevity and decrease in the number of qualified donors, the need to find alternative solutions to current organ replacement methods is rapidly becoming a critical issue.
Health-wise, there are few things that will make as big of an impact on our longevity and decreased stress-levels as having a circle of friends.
Consistent with this scenario, a recent study in which functional NPC1 protein was expressed in an astrocyte-specific manner in Npc1−/− mice was reported to lead to increased longevity and decreased neuronal storage of cholesterol [44].
Mehta et al reported that vhl-1 or egl-9 RNAi increased C. elegans longevity and decreased the toxic effects of transgenes that expressed polyglutamine repeats or beta amyloid.
