Heavy water (D2O) extends the life of the yeast by 80%, fruit flies by 30%, nematodes 10%

Heavy water (D2O) extends the life of the yeast by 80%, fruit flies by 30%, nematodes 10%  3r3104. Deuterium Solution (concentration of 25%) and usual water
 3r3104. Despite the fact that some combinations of geroprotectors or 3r311. Yamanaki factors
(converting normal cells into pluripotent) are capable of extending life by more than 50% to mice, with deuterium and other stable isotopes, a precedent is important.

 3r3104. The first to suggest the use of deuterium isotope for biological effects is our compatriot 3r3r177. Mikhail Shchetinov
.

 3r3104. While we think isotopes exhibit identical chemical behavior, this is not entirely accurate. Isotopes exhibit a subtle difference in chemical bond strength. The heavier the isotope, the stronger the bond. For example, carbon-deuterium bond is 5-10 times stronger than carbon-hydrogen. Deuterium is much heavier than hydrogen compared to carbon-13 (+1 neutron) and carbon (atomic mass 12). Previous studies have shown that the amount of free radicals decreases in isolated rat mitochondria exposed to heavy water.

 3r3104. The experiment was inspired by the fact that in old age the content of heavy isotopes (carbon-1? deuterium, nitrogen-1? oxygen-1? sulfur-34) in amino acids falls. Most likely that in metabolites too.
 3r3104.
 3r3104. Schetinov founded the biotechnology firm 3r3333. Retrotope
which is currently engaged in clinical studies of rt001 rt00? which are deuterium-modified fatty acids (such as omega 3) for the treatment of Parkinson's disease and Friedreich's Ataxia (mitochondrial disease).

 3r3104. In animals, a solution of heavy water was able to normalize high blood pressure caused by a high salt diet in rats, possibly through the suppression of hypertension associated with an increase in calcium absorption. This effect will certainly prolong life.
 3r3104.
 3r3104. Deuterium and carbon-13 are also apparently non-toxic. Mice are perfectly normal, even when 60 percent of the carbon atoms in their bodies are carbon-13. Decades of experiments in which animals received heavy water indicate that up to one fifth of the water in your body can be replaced with heavy water without any side effects.
 3r3104.
 3r3104. Similar experiments were carried out on humans, albeit with lower levels of deuterium. One recent experiment kept people on a low-level, heavy-water diet for 10 weeks, during which their heavy water levels increased to about 2.5% of body weight without any side effects (Biochimica et Biophysica Acta, vol 176? p 730) .
 3r3104.
 3r3104. Heavy water, however, is not completely safe. In mammals, the toxic effect begins somewhere at 20%, and at a dose of 35% is lethal. This is largely due to the effect of the isotope - every protein in your body has the potential to take a deuterium atom of heavy water instead of hydrogen, and once this radically changes the entire biochemistry. It still takes a considerable amount of heavy water to suffer from any painful effect - 5 milliliters will not hurt you with anything, but even startups like Retrotrope do not advertise heavy water as the elixir of life.

 3r3104. While Retrotope is concentrating on aging, Schepinov says that there are other uses for the isotope effect that he would like to explore. One of them protects long-term space travelers from the effects of cosmic rays and other ionizing radiation, which are as damaging as aging.
 3r3104.
 3r3104. Another possibility is to produce meat, eggs, or milk, enriched with deuterium or carbon-1? by feeding deuterated water or enriched with isotopes of amino acids for farm animals.
 3r3104.
 3r3104. The idea of ​​using chemical isotopes to fight aging can be new, but nature is already acting in this way to protect us from free radical attack, which is considered the main cause of aging. Babies and mice are born with much more carbon-13 isotope in their bodies than their mother, and women appear to become unusually depleted in carbon-13 during their birth. Both findings suggest an active transfer of carbon-13 from mother to fetus. This will have a good evolutionary meaning, since many of the proteins and DNA molecules formed at an early stage should be with us all our lives. "Every single atom in the DNA of a 100-year-old's brain is the same atom as when he was 15 years old."
 3r3104.
 3r3104. Another obstacle Retrotope will have to overcome the cost. At current prices, a liter of heavy water costs you $ 300. “Isotopes are expensive,” says Shchepinov. “But no one needs them to be cheap. Methods to get them there, but nobody wants them. ” If demand does not increase, there is no incentive to produce them in bulk, and this holds a high price.
 3r3104.
 3r3104. Also the proportion of heavy isotopes in metabolites and amino acids can serve as a biomarker of human age.

 3r3104. It would be interesting to discover if a mouse fed with a certain concentration of deuterium oxide would also live longer
