Rejuvenation of the membranes of aging nerves: and here young blood will help

As a result of the experiment on connecting the blood flows of old and young mice, the remyelination of the nerve sheath in elderly rodents began to go as well as in young animals.

Cord Blood Stem Cells against Type 1 Diabetes

Umbilical cord blood stem cells "retrain" T-lymphocytes of patients with type 1 diabetes, which partially restores insulin synthesis in the pancreas.

To the attention of the fat and lazy: do you want a shot instead of physical education?

Injections of airizine will not make a Schwarzenegger choke, because this hormone is not involved in building muscle mass. But perhaps the drugs developed on its basis will be able to replace physical education for lazy people and gluttons :)

Genome for a thousand dollars: we are going to the finish line

There is not much left until the end of the race for the sequencing of the personal genome for 1 thousand dollars and one day: if this barrier is not overcome this year, then they will take it next.

Prostate cancer, get drunk on poison!

"Smart" nanoparticles are able not only to distinguish between cancer and healthy prostate cells with absolute reliability, but also to penetrate into tumor cells, delivering the drug exactly to the target.

Chimera monkeys

The bodies of each of the three monkeys born at the Oregon Primate Research Center consist of a mixture of cells from six embryos. In each of the chimera macaques born, there are tissues containing six different genomes.

Probiotics increase life expectancy

If the results of clinical studies confirm the data of experiments on mice, probiotic bacteria of the LKM512 strain will help to increase human life expectancy and improve the health of the elderly.

Young stem cells slow down aging

The introduction of young stem cells did not lead to a complete cure of progeria in mice, but perhaps the results obtained will help develop ways to prolong life with normal aging.

Nicotine helps with senile dementia

The use of nicotine patches improved the mental abilities of non-smoking patients with senile dementia.

Take a nanopile!

The project provides for the production of three groups of pharmaceuticals with carriers made of porous silicon and other nanomaterials – solid dosage forms with prolonged action, vaccines and organogels.

Life extension: resveratrol, spermidine and autophagy – references

Life extension: Resveratrol, spermidine and autophagy (3)

The final confirmation of the hypothesis about the relationship between increased autophagy activity and healthy aging of mammals, especially humans, would revolutionize the entire field of research on aging mechanisms.

Life extension: Resveratrol, spermidine and autophagy (2)

Induction of autophagy with the help of pharmacological agents can increase the duration of a healthy life. It is very likely that autophagy not only protects cells, but also slows down aging at the organizational level.

Life extension: Resveratrol, spermidine and autophagy (1)

Autophagy is traditionally considered a mechanism of self-destruction of cells, but there is more and more evidence that the launch of autophagy is necessary for the implementation of cytoprotective and /or aging-slowing effects of spermidine and resveratrol.

Stem cells against age-related hearing loss

Kiel University specialists are planning to transplant fibrocytes grown from stem cells – precursors of mature connective tissue cells - into the inner ear of patients with age-related hearing loss.

Nanotechnology: the best of 2011

Most of the most interesting nanotechnology developments in 2011 are related to nanomedicine.

Vaccine against autoimmune diseases

Biologists from the Weizmann Institute forced the immune system of animals to fight the disease associated with errors in the work of this system itself. For the virtuoso deception of the body, the authors used synthetic substances that imitate natural ones.

RNA computer-aided design system

A group of biologists from the University of California at Berkeley has created, as they call their technology, a "computer-aided design system" (CAD) for the synthesis of RNA molecules with specified properties.

Nanovitaminated drinks are healthier than regular ones

Researchers from Israel have created nanocapsules from natural food materials that can be loaded with fat-soluble vitamins and other lipophilic micronutrients that are beneficial to health.

Simulation of the human brain: wait for the first results

The goal of the Human Connectome project is a complete description of the connections between the neurons of the human brain and the identification of correlations between the structure of neural networks and mental abilities, as well as the behavior of a particular person.
