Reduction of DILP2 in Drosophila triages a metabolic phenotype from lifespan revealing redundancy and compensation among DILPs [PDF]
, 2008 The insulin/IGF-like signalling (IIS) pathway has diverse functions in all multicellular organisms, including determination of lifespan. The seven insulin-like peptides (DILPs) in Drosophila are expressed in a stage- and tissue-specific manner.

Identification of sur2 mutation affecting the lifespan of fission yeast [PDF]
, 2021 Yeast is a suitable model system to analyze the mechanism of lifespan. In this study, to identify novel factors involved in chronological lifespan, we isolated a mutant with a long chronological lifespan and found a missense mutation in the sur2^+ gene ...

Hormonal changes during salinity-induced leaf senescence in tomato (Solanum lycopersicum L.) [PDF]
, 2008 Leaf senescence is one of the most limiting factors to plant productivity under salinity. Both the accumulation of specific toxic ions (e.g. Na+) and changes in leaf hormone relations are involved in the regulation of this process. Tomato plants (Solanum

The gustatory system influences "Drosophila" lifespan [PDF]
, 2011 The lifespan of an organism is affected by the complex interplay between genetic and environmental factors. In C. elegans, this interaction between genes and environment is mediated by the sensory system.

Extension of Yeast Chronological Lifespan by Methylamine [PDF]
, 2012 Background: Chronological aging of yeast cells is commonly used as a model for aging of human post-mitotic cells. The yeast Saccharomyces cerevisiae grown on glucose in the presence of ammonium sulphate is mainly used in yeast aging research.

Methylation of ribosomal RNA by NSUN5 is a conserved mechanism modulating organismal lifespan [PDF]
, 2015 Several pathways modulating longevity and stress resistance converge on translation by targeting ribosomal proteins or initiation factors, but whether this involves modifications of ribosomal RNA is unclear.

Identification of a novel protein kinase that affects the chronological lifespan in fission yeast [PDF]
, 2017 Chronological lifespan is defined by how long a cell can survive in a non-dividing state. In yeast, it is measured by viability after entry into the stationary phase.

Efficiency of the use of ryegrass by heifers in response to the receival of supplement
Acta Scientiarum: Animal Sciences, 2017 The intensity and frequency of defoliation of ryegrass (Lolium multiflorum Lam.) by beef heifers exclusively grazing or receiving corn grain or extruded commercial product with fat as supplement were evaluated.
