Reduction of DILP2 in Drosophila triages a metabolic phenotype from lifespan revealing redundancy and compensation among DILPs [PDF]

open access: yes, 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]

open access: yes, 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 ...

The gustatory system influences "Drosophila" lifespan [PDF]

open access: yes, 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]

open access: yes, 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.

Molecular evolution and functional characterization of Drosophila insulin-like peptides [PDF]

open access: yes, 2010
Multicellular animals match costly activities, such as growth and reproduction, to the environment through nutrient-sensing pathways. The insulin/IGF signaling (IIS) pathway plays key roles in growth, metabolism, stress resistance, reproduction, and ...

Methylation of ribosomal RNA by NSUN5 is a conserved mechanism modulating organismal lifespan [PDF]

open access: yes, 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.

Day2day: investigating daily variability of magnetic resonance imaging measures over half a year

open access: yesBMC Neuroscience, 2017
Background Most studies of brain structure and function, and their relationships to cognitive ability, have relied on inter-individual variability in magnetic resonance (MR) images.

Identification of a novel protein kinase that affects the chronological lifespan in fission yeast [PDF]

open access: yes, 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.

Obstructive Sleep Apnea and Circulating Potassium Channel Levels

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundCardiac arrhythmias and sudden cardiac death are more frequent in patients with obstructive sleep apnea (OSA). OSA is associated with QT prolongation, and QT prolongation is an independent risk factor for sudden cardiac death.

Incentive motivation improves numerosity discrimination in children and adolescents

open access: yesScientific Reports, 2022
We recently showed that incentive motivation improves the precision of the Approximate Number System (ANS) in young adults. To shed light on the development of incentive motivation, the present study investigated whether this effect and its underlying ...
