Spermidine is linked to higher fitness in coronary artery disease

Each doubling of spermidine intake was associated with 2.6 millilitres per kilogram per minute higher peak oxygen uptake in older people with coronary artery disease.Each doubling of spermidine intake was associated with 2.6 millilitres per kilogram per minute higher peak oxygen uptake in older people with coronary artery disease.

Two PDE4 inhibitors extend lifespan in worms

In laboratory experiments, roflumilast and rolipram lengthened roundworm lifespan by activating a signalling pathway that improved mitochondrial function and alleviated…In laboratory experiments, roflumilast and rolipram lengthened roundworm lifespan by activating a signalling pathway that improved mitochondrial function and alleviated oxidative stress.

Early overfeeding speeds muscle loss and shortens life in mice

Overfeeding young mice damaged gut microbes, impaired muscle cell energy production, and worsened age-related muscle wasting in later life.Overfeeding young mice damaged gut microbes, impaired muscle cell energy production, and worsened age-related muscle wasting in later life.

Bacterial molecule shapes behaviour and lifespan in worms

A screen of 3,985 bacterial strains identified an iron-gathering molecule whose effects in worms depended on a stress response in cells’ energy-producing structures.A screen of 3,985 bacterial strains identified an iron-gathering molecule whose effects in worms depended on a stress response in cells’ energy-producing structures.

A bone hormone reverses age-related movement decline in mice

In mice, restoring the hormone osteocalcin improved motor function in old age by supporting cellular recycling and energy production in spinal motor neurons.In mice, restoring the hormone osteocalcin improved motor function in old age by supporting cellular recycling and energy production in spinal motor neurons.

Ketogenic diet improved heart function in aged mice

An eight-week experiment in 22-month-old mice found comparable benefits in males and females given a ketogenic diet rather than standard chow.An eight-week experiment in 22-month-old mice found comparable benefits in males and females given a ketogenic diet rather than standard chow.
