Can AI Predict Your Death?: Once confined to the realms of science fiction or relatively crude internet death calculators, AI-driven predictions about longevity are inching closer to reality. Questions about the accuracy and value of these forecasts remain.
The Best Talks From Longevity Summit 2024: Earlier this month, for the third year in a row, the famed Buck Institute for Research on Aging hosted the Longevity Summit. This two-day event was organized by Longevity Global, a community of longevity researchers, investors, and enthusiasts, and its founder Dr. Christin Glorioso.
Research Roundup
A Clinical Trial of a Three-Part Treatment for Inflammaging: Reseachers publishing in Antioxidants have combined three antioxidant and anti-inflammatory compounds and tested their effects in human beings. The researchers hold that this supplement combination has significant effects on oxi-inflammaging, a combination of oxidative stress and inflammaging that has been suggested to have significant effects on lifespan.
Resveratrol, Vitamin C Drop Oxidative Stress After Menopause: In a randomized, controlled trial published in Nutrients, researchers tested supplementation with resveratrol, vitamin C, and a combination of both. They learned that all of the treatments had a similar positive impact on oxidative stress in postmenopausal women.
AI Outperforms AI-Assisted Doctors in Diagnostic Reasoning: In a new study, ChatGPT 4.0 achieved significantly better diagnostic scores when evaluating complex cases than either unassisted human physicians or physicians who consulted the chatbot.
Fragmented Mitochondria Linked to Muscle Weakness: In a study published in Aging Cell, researchers have outlined a relationship between mitochondrial fragmentation in skeletal muscle and the loss of strength with age. As exercise is associated with mitochondrial fusion and one study had suggested that six months of endurance training can compensate for 30 years of aging, the authors suggest that further research on exercise in older people should be done with a close examination into mitochondrial changes.
Nuclear Expression of a Mitochondrial Gene in Mice: Scientists from the Longevity Research Institute (LRI), which was formed by the merger of SENS Research Foundation and Lifespan.io, have achieved expression of an essential mitochondrial gene in the nucleus and proper functioning of the protein. This could pave the way for curing diseases caused by mitochondrial mutations.
Senescent Cells Protect the Bladder: In Aging Cell, a research team has explained why barrier cells in the human bladder are largely senescent and what might lead them to become cancerous. The researchers note that these senescent cells are clearly necessary for proper function of the bladder, suggesting that they should be treated rather than destroyed, such as by improving their mitochondrial function or reducing their oxidative stress.
Extending Monkeys’ Reproductive Span With Stem Cells: An investigation into transplanting human embryonic stem cells (hESC)-derived MSC-like cells (M cells) into the ovaries of cynomolgus monkeys suggests an extension of female reproductive span accompanied by a reduction in senescence-associated processes, such as inflammation, fibrosis, oxidative damage, and apoptosis.
Encouraging Hair Growth by Reducing Senescence: In Aging Cell, researchers have described how to improve the hair growth potential of stem cells and organoids by reducing cellular senescence. The researchers hold that senolytics are key in overcoming one of the major hurdles associated with this line of work.
A Senolytic Approach to Faster Wound Healing: Researchers have published in Aging their findings that a senolytic compound accelerates wound healing in aged mice when it is administered before the wound occurs.
Lower Rates of Epigenetic Aging in Olympic Champions: A recent investigation into Hungarian Olympic champions suggests slower epigenetic aging and differences in gene methylation patterns between champions and non-champions.
How Cellular Reprogramming Affects Mitochondrial Dysfunction: Creating induced pluripotent stem cells (iPSCs) causes mutant mitochondrial populations to change, and researchers have investigated this phenomenon more thoroughly.
Associations of accelerometer-measured physical activity, sedentary behaviour, and sleep with next-day cognitive performance in older adults: Memory benefits of physical activity may persist for 24 hours; longer sleep duration, particularly more time spent in slow-wave sleep, could independently contribute to these benefits.
Dietary inflammatory potential and the risk of cognitive impairment: A meta-analysis of prospective cohort studies: This meta-analysis suggests that a higher dietary inflammatory potential is independently associated with an increased risk of cognitive impairment.
Association between dietary inflammatory index score and incident dementia: Higher DII scores were associated with a higher risk of incident all-cause dementia and Alzheimer’s.
Dietary flavonoid intake is negatively associated with accelerating aging: an American population-based cross-sectional study: This study has found that most influential flavonoids are flavones, flavanones, flavan-3-ols, and flavonols.
A phase 2 pilot study of umbilical cord blood infusion as an adjuvant consolidation therapy in elderly patients with acute myeloid leukemia: These findings suggest that UCB infusion is an effective and safe post-remission adjuvant therapy for elderly AML patients.
Metabolomic age (MileAge) predicts health and life span: A comparison of multiple machine learning algorithms: This metabolomic aging clock can be applied in research and may find use in health assessments, risk stratification, and proactive health tracking.
Intestinal mucosal barrier repair and immune regulation with an AI-developed gut-restricted PHD inhibitor: ISM012-042 restores intestinal barrier function and alleviates gut inflammation in multiple experimental colitis models.
Exploring the potential of plasma and adipose mesenchymal stem cell-derived extracellular vesicles as novel platforms for neuroinflammation therapy: Overall, this study highlights the potential of EVs loaded with DNZ as a novel approach for treating neuroinflammation underlying various neurodegenerative diseases.
Comparative Analysis of the Therapeutic Potential of Extracellular Vesicles Secreted by Aged and Young Bone Marrow-Derived Mesenchymal Stem Cells in Osteoarthritis Pathogenesis: These findings highlight that donor age is a critical determinant in the therapeutic potential of BMSC-derived EVs for clinical use in OA treatment.
In vivo AAV9-Myo7a gene rescue restores hearing and cholinergic efferent innervation in inner hair cells: Restoration of IHC function using AAV-Myo7a rescue re-establishes the synaptic profile of adult IHCs, leading to the amelioration of hearing loss.
Telomerase reverse transcriptase gene knock-in unleashes enhanced longevity and accelerated damage repair in mice: These findings foreshadow the potential of TertKI as an extraordinary rejuvenation force, promising not only longevity but also rejuvenation in skin and intestinal aging.
Improved Therapeutic Efficiency of Senescent Cell-specific, Galactose-Functionalized Micelle Nanocarriers: This novel formulation showed reduced delivery and toxicity to non-senescent cells, thereby increasing the senolytic index of Navitoclax and making it suitable for future in vivo experimental designs to improve selectivity and safety profiles.
Association of urban green and blue space with accelerated ageing: A Cohort Study in the UK Biobank: UGBS with a composite weighted score showed a better correlation with accelerated ageing than green spaces.
