Rapamycin reduces the total amount of senescent cells

Rather than simply modifying senescent cells present in the tissue, rapamycin treatment either reduces the number of cells entering senescence or increases the clearance of senescent cells

Privacy policy on bio data which restricts to share for AI training on such data kills not only the owners of this data, but kills all of us.

These AI trainings can find solutions on fighting severe diseases which kill EVERY DAY 166,000 people

There should be the international law obligating everyone to share their bio data in anonymous way for radical life extension purposes.

We, in Longevity InTime, use the anonymization token, which anonymizes on the client’s end l sensitive private data (names, contacts, social security numbers & etc) and gives values of these client’s bio data parameters (e.g. glucose, cholesterol, blood pressure rate & dozens of other parameters) to data scientists in the anonymized token number, which can be associated with end user (if needed) only by the end user itself. For the rest of the world this data belongs to the token (random numbers).

The other thing, that AI can save and extend lifespan. In 500,000 hours (approximately) everyone who was involved in this discussion will die due to “natural causes”. But these natural causes can de delayed or one day even cancelled by AI. This is not just a thought, it is evidence based science.

It’s the greatest tragedy that people with such serious faces, questions and answers are focusing on the fractions of the picture (potential threat & etc), they don’t see the picture itself (that we live 30-40 years less than physically can, up to 120). If there are more than 600 recorded cases of people lived over 110 years then its possible and AI can try to do it!

Just imagine only 600, out of 109 billion of people who lived until know, plus 8 billion who lives now and big part of them will die in just 500,000 hours.

We, in Longevity InTime, use AI for simulation of clinical trials, that can speed up the outcomes of these trials and destroy so to called “longevity paradox”. When trials organizers & participants die before the end of the clinical trials process, due to natural causes, because trials take decades.

Long but revealing as well as entertained article that covers interesting paths and views from scientists such as Charles Brenner (known as "the longevity skeptic"), David Sinclair and Leonard Guarente.

“The field of gene therapy has made massive advancements in the last 10 years with 15 approved gene therapies. BUT some of the evidence for those approved therapies were evident in the 1990s! So regulations are still slow. They are speeding up but there is still not one aging-related or regenerative gene therapy in clinical trials (outside of follistatin that started over a decade ago for muscular dystrophy). Things are speeding up but for 110,000 people today it is too late. And this trend continues.”

Restoring Protein Elastin
Introduction:
• Our skin contains two essential proteins, elastin and collagen, which support the elasticity, resilience, and general young look of our skin. Since birth, elastin has allowed the skin to stretch and rebound, while collagen offers resilience and structural support.
• However, as we get older, the synthesis of these proteins declines, which causes the skin to lose its firmness and suppleness. Fortunately, there are a number of actions you can do to help the recovery and upkeep of collagen and elastin.
• Adopting a balanced diet high in important nutrients, shielding the skin from damaging UV rays, utilising topical treatments with healthy components, thinking about dermatological procedures, establishing good living habits, and placing a priority on getting enough sleep are a few examples.
• Our skin's elasticity and resilience are provided by the protein elastin, which is a vital part of our skin. While it is true that as we age, our ability to produce elastin declines, there are a number of things you can do to help your skin's elastin and collagen levels return to normal. Here are some recommendations based on research:
Details:
• Support via nutrition: Eating a diet that is well-balanced and rich in nutrients that support skin health might be helpful. Vitamins A, C, and E are important nutrients because they are antioxidants that help prevent oxidative damage to collagen and elastin. Additionally, the creation of collagen and elastin depends on minerals like copper and zinc. You may help supply these nutrients by including foods like fruits, vegetables, lean meats, whole grains, nuts, and seeds in your diet.
• Hydration: It's important to drink enough water to keep your skin healthy. Drinking adequate water facilitates the delivery of nutrients to the cells, particularly those responsible for the production of elastin and collagen, and keeps your skin moisturised.
• Sun protection: Prolonged sun exposure can cause the collagen and elastin fibres in the skin to break down more quickly. Maintaining these proteins requires that you protect your skin from the sun. When going outside, be careful to use a broad- spectrum sunscreen with a high SPF, wear protective clothes, and look for shade during the hottest parts of the day.
• Treatments that are applied topically: Some topical therapies may support the skin's elastin and collagen development. Look for skincare products with retinoids, peptides, vitamin C, and hyaluronic acid as components. These compounds have the potential to increase the skin's ability to produce collagen and elastin.
• Dermatological treatments: A variety of dermatological procedures can enhance the synthesis of collagen and elastin. These include of radiofrequency therapy, microneedling, and laser treatments. By boosting the synthesis of these proteins, these techniques help to rejuvenate the skin.

• Lifestyle factors: Your skin's health may be affected by certain lifestyle choices. Elastin and collagen integrity can be preserved by refraining from smoking and consuming less alcohol. Alcohol abuse can hinder collagen production, whereas smoking has been related to increased elastin breakdown.
• Adequate sleep: A good night's sleep is crucial for maintaining good skin health. The body regenerates tissues, including the skin, while we sleep. To promote healthy skin function and regeneration, aim for 7-9 hours of unbroken sleep each night.
Elastin and collagen maintenance and restoration in the skin:
• Retinoids: Retinoids are vitamin A derivatives that have been extensively researched for their capacity to increase the formation of collagen and enhance the look of ageing skin. They function by enhancing cell renewal and enhancing the production of collagen and elastin fibres. Retinoids come in over-the-counter medicines like retinol and prescription-strength formulations like tretinoin.

When taking retinoids, it's crucial to adhere to your dermatologist's instructions and suggestions because they can make skin sensitive and should be added to your skincare regimen gradually.
• Peptides: serve as the building blocks for proteins like collagen and elastin. Peptides are short chains of amino acids. Some peptides have the ability to tell the skin to make more collagen and elastin when administered topically. Palmitoyl pentapeptide and copper peptides are two examples of peptides that are frequently utilised in cosmetics.
• Vitamin C: Vitamin C is a powerful antioxidant that is essential for the production of collagen. Collagen fibres benefit from its stabilising and free radical-damage prevention properties. Additionally, vitamin C has a role in the transformation of the amino acid proline into hydroxyproline, which is required for collagen synthesis. To encourage the production of collagen and the general health of your skin, look for serums or creams containing vitamin C (ascorbic acid).
• Hyaluronic Acid: A naturally occurring component in the skin, hyaluronic acid aids in moisture retention and adds to the plumpness and flexibility of the skin. Although it doesn't directly promote the formation of elastin or collagen, it can improve the skin's look by increasing moisture and lessening the visibility of fine lines and wrinkles. Serums and moisturisers are only two examples of skincare products that include hyaluronic acid.
• Microneedling: Microneedling is a technique that uses small needles to make channels in the skin. As the skin heals itself, this process encourages the creation of collagen and elastin. Microneedling can be performed with a dermatologist's assistance or at home using dermarollers, although professional treatments often provide more noticeable results.
• Radiofrequency Therapy: Radiofrequency (RF) therapy employs radiofrequency radiation to heat the deep layers of the skin in a non-invasive manner. The regulated heat helps to tighten and firm the skin by stimulating the creation of collagen and elastin. A licenced aesthetician or dermatologist can provide RF treatment.

Conclusion:
• Despite the fact that the synthesis of elastin and collagen in our skin naturally declines as we age, there are proactive measures we can take to assist their repair and maintenance.
• We can encourage the creation and preservation of these essential proteins by using a comprehensive strategy that includes good diet, sun protection, topical treatments, dermatological procedures, healthy lifestyle choices, and enough sleep.
• While these steps might not completely reverse the effects of ageing on elastin and collagen, they can help create healthier, more elastic, and resilient skin, which helps keep our skin strong and youthful-looking as we age.

Topical Rapamycin
Introduction:
A drug called topical rapamycin is employed in a number of dermatological procedures. It originates from the immunosuppressive qualities of the naturally occurring substance known as rapamycin, which was first found in the soil of Easter Island.
It has been demonstrated that rapamycin lowers the body's overall senescent cell count. The term "cellular senescence" describes a condition in which cells no longer have the capacity to divide and proliferate and instead experience a persistent and irreversible growth stop.
Senescent cells build up with ageing and have a role in a number of age-related illnesses and ailments. Will discuss more about Rapamycin below.
"Rapamycin reduces the total amount of senescent cells”
• It has been revealed that rapamycin, a drug produced from the substance first identified on Easter Island, has the capacity to lessen the overall amount of senescent cells in the body. Age-related cell accumulation of senescent cells, which are cells that have reached an irreversible growth halt.
• Rapamycin causes a process known as autophagy, which includes the recycling and destruction of damaged cellular components, by blocking a protein known as mTOR (mammalian target of rapamycin). Senescent cells and cell waste are removed via autophagy.
• Rapamycin therapy has been shown in several trials to reduce the number of senescent cells in a variety of organs, including the skin, liver, and adipose tissue. In several animal models, this decrease in senescent cells has been linked to a number of positive outcomes, including better tissue function, higher regenerative ability, and prolonged life.
• Studies on anti-aging and age-related diseases are increasingly focusing on the treatment of senescent cells. Senescent cell burden reduction is thought to offer therapeutic promise for a number of illnesses, including cancer, neurological disorders, and cardiovascular ailments.
• To completely comprehend the effects of rapamycin, including ideal dose and possible adverse effects, further study is still required. The effectiveness and safety of rapamycin and other senolytic treatments in humans are now being studied in clinical studies.
• The medication rapamycin is a member of the group of substances known as mTOR inhibitors. A protein kinase known as mTOR (mechanistic target of rapamycin) is essential for cell growth, metabolism, and ageing.
• Rapamycin has been shown to have potential anti-aging properties and has been found to alter a number of cellular processes via blocking mTOR.
