Curiosity about how well our bodies are ageing has fuelled an industry around telomere length tests, but the much touted “biological clock” in our DNA isn’t what we thought.
Modifying brain cell activity can extend the lifespan of fruit flies while also preventing the damage characteristic of Alzheimer’s disease, finds a new study led by UCL researchers.
This is a detailed summary of plasma dilution and at 58:38 the future is explained where they will publish human results from 25 people, then start a company whose first order of business will be phase 3 trials with more people and placebo and hopefully funding. It appears you can pay to have the procedure. The hopeful start is this year in may.
Irina will present her recent findings on plasma dilution, showing that age-reversing effects, such as rejuvenating tissues in mice, can be achieved by.
diluting the blood plasma of old mice: Rejuvenation of three germ layers tissues by exchanging old blood plasma with saline-albumin.

Join us for Dr. Matt Kaeberlein’s presentation. He is the Founding Director of the UW Healthy Aging and Longevity Research Institute, and founder and co-Director of the Dog Aging Project and a Professor of Laboratory Medicine and Pathology at the University of Washington (UW) School of Medicine, with Adjunct appointments in Genome Sciences and Oral Health Sciences. Dr. Kaeberlein’s research interests are focused on biological mechanisms of aging in order to facilitate translational interventions that promote healthspan and improve quality of life.

As people get older, their neural stem cells lose the ability to proliferate and produce new neurons, leading to a decline in memory function. Researchers at the University of Zurich have now discovered a mechanism linked to stem cell aging—and how the production of neurons can be reactivated.
A trio of researchers with ICAEV, Universidad Austral de Chile, and the University of Liverpool, respectively, have found suppressor genes linked to longevity and less cancer in two species of whales. In their paper published in the journal Proceedings of the Royal Society B, Daniela Tejada-Martinez, João Pedro de Magalhães and Juan C. Opazo, describe their genetic study of longevity in cetaceans and what they learned.

Hi everybody. Around 10 days ago, I participated in an online conference about aging, organized by HEALES and ILA, and Harold Katcher was one of the speakers. As each speaker had only 15 minutes for their presentation (and Harold spoke only for 10 minutes because he had some technical issues with Zoom), I thought that it would be a good idea to make an interview with him so that he has more time to speak about his rejuvenation therapy with E-5, the test with dogs, the timeframe for the arrival of the therapy for humans, and, above all else, his theory of aging. So, it’s a more informal conversation, but I think it helps everybody to know more about Harold Katcher, maybe one of the most (if not the most) influent people in human history.
Harold Katcher, one of the discoverers of the human breast cancer gene and possibly the discoverer of the greatest rejuvenation therapy to date, talks to Nicolas Chernavsky about his rejuvenation therapy with E-5, his carreer and his theory of aging. 2020 paper on experiments with E-5: https://www.biorxiv.org/content/10.1101/2020.05.07.082917v1.…1.full.pdf Harold’s 2013 paper on aging: https://link.springer.com/article/10.1134/S0006297913090137 Conboy’s 2005 paper on parabiosis: https://www.biorxiv.org/content/10.1101/2020.05.07.082917v1.…ature03260 1994 paper on human breast cancer gene: https://courses.washington.edu/gs466/readings/miki.pdf Find out more about Nicolas Chernavsky and NTZ on www.ntzplural.com #rejuvenation #aging #biotechnology #health #science.
Muscle constitutes the largest organ in humans, accounting for 40% of body mass, and it plays an essential role in maintaining life. Muscle tissue is notable for its unique ability for spontaneous regeneration. However, in serious injuries such as those sustained in car accidents or tumor resection which results in a volumetric muscle loss (VML), the muscle’s ability to recover is greatly diminished. Currently, VML treatments comprise surgical interventions with autologous muscle flaps or grafts accompanied by physical therapy. However, surgical procedures often lead to reduced muscular function, and in some cases result in a complete graft failure. Thus, there is a demand for additional therapeutic options to improve muscle loss recovery.
A promising strategy to improve the functional capacity of the damaged muscle is to induce de novo regeneration of skeletal muscle via the integration of transplanted cells. Diverse types of cells, including satellite cells (muscle stem cells), myoblasts, and mesenchymal stem cells, have been used to treat muscle loss. However, invasive muscle biopsies, poor cell availability, and limited long-term maintenance impede clinical translation, where millions to billions of mature cells may be needed to provide therapeutic benefits.
Summary: FOXO3, a gene linked to longevity in humans, protects neural stem cells from the negative effects of stress.
