Vessels are to blame for senile muscle weakness

In old age, insulin ceases to have a vasodilating effect on the smallest muscle capillaries, which leads to a violation of protein synthesis and muscle tissue renewal processes.

Nervous mechanisms of aging and cognitive decline

One of the main health problems faced by the aging generation is the extinction of cognitive function. The mechanisms underlying these processes need to be considered in the context of the molecular biology of the aging process.

Another way to prolong life: arrest arrestin

Removal of the arrestin gene from the genome of nematodes led to an increase in the lifespan of these organisms by 30%, while a three-fold increase in the expression of this gene reduced it by 30%.

Aging and ways to prolong life: taking lessons from yeast

Many of the most important mechanisms of aging have hardly changed over billions of years of evolution and work not only in yeast, but also in mammals. The study of yeast aging made it possible to find the most promising geroprotectors currently being developed.

Aging issues: a special application to Nature

The issue includes several reviews describing the results of recent studies on various aspects of aging and the possibility of applying the results obtained to prevent age-related diseases and prolong human life and youth.

Old man's memory: alignment with the best!

A new approach to the study of age–related memory changes – the study of the brain of people who have retained a good memory until old age - will make it possible to establish what exactly allows such people to avoid senile senility.

The "invisible hat" will not allow Alzheimer's disease to develop?

Microglia – immune cells of the nervous system – destroys neurons in the brains of mice suffering from Alzheimer's disease, under the influence of signaling proteins synthesized by the neurons themselves. It remains only to learn how to block these signals.

Sestrin protein is a natural retarder of aging processes

The developers of "tablets for old age" have another potential target – the human analogue of the protein Sestrin, whose ability to slow down the aging process and the development of age-related diseases is shown for fruit flies.

Don't want to get old? Set up the biological clock!

Perhaps, in addition to participating in the "tuning" of the biological clock, the per gene controls the mechanism that ensures the restoration of oxidative damage. Disruption of its functioning leads to accelerated aging, which can manifest itself in the development of a whole range of pathological conditions, including neurodegenerative diseases, cardiovascular diseases and cancer.

Aging is reversible

However, so far at the level of individual cells of people suffering from premature aging. The transformation of their fibroblasts into induced pluripotent stem cells lengthens their telomeres and activates telomerase.

Senile insomnia? No, you're all right!

The process of normal aging is accompanied by a decrease in the duration and depth of sleep necessary to ensure daytime wakefulness. At the same time, healthy old people feel less sleepy during the day than young people.

Rejuvenate with growth hormone? Thank you, no need!

A study of a unique population of Brazilian dwarfs has shown that growth hormone deficiency does not affect life expectancy. Unfortunately, these data are unlikely to reduce the number of offers to rejuvenate with injections of somatotropic hormone.

Pathophysiology of aging, longevity and age-related diseases

On April 18, 2007, the international conference "Pathophysiology of Aging, longevity and age-related diseases" was held in Palermo, Italy. In the proposed report, we present basic information about the most important issues discussed.

The high bar of aging

Successful aging is a matter that concerns not only the elderly. This is something we can work on all our lives.

Prolonging life and preventing cancer: less sugar!

Scientists have calculated two key genes that regulate the cellular response to sugar deficiency. The first one, hTERT, encodes the enzyme telomerase, which allows cells to divide indefinitely. The second, p16, encodes a protein that suppresses tumor development.

Prolonging life and protecting against Alzheimer's disease

Life expectancy in mice with reduced activity of the IGF-1-mediated signaling mechanism increased by 35%. And, despite the brains clogged with amyloid plaques, they did not show symptoms of Alzheimer's disease until old age.

Age-related infectious disease: loneliness

Lonely elderly people can "infect" others with their mood: their acquaintances and neighbors subsequently gradually move away from people, eventually being eliminated from society as a whole.

Strong muscles protect against Alzheimer's disease

Physical activity as such is not related to the development of Alzheimer's disease: it is strength that is important, not how much a person spends in motion, how his lungs work and what body weight is.
