In conclusion, although the contribution of CRF to GrimAgeAccel and FitAgeAccel is relatively low compared to lifestyle-related factors such as smoking, the results suggest that the maintenance of CRF is associated with delayed biological ageing in older men. « Back to Top Release of Acetylcholine is Necessary for the Aging Brain to Compensate for a Lack of Neurogenesis https://www.fightaging.org/archives/2023/09/release-of-acetylcholine-is-necessary-for-the-aging-brain-to-compensate-for-a-lack-of-neurogenesis/ Neurogenesis is the process by which new neurons are created by neural stem ce...

Peptoid Oligomers Target Viral Membranes
Researchers at New York University have developed a new method to target many viruses that cause disease. For viruses with a lipid membrane, which includes many that commonly cause disease, this new technique could prove to be fatal. By targeting the...

This study demonstrates just how vital the thymus is to maintaining adult health." « Back to Top Does Amyloid-β Aggregation Cause Broad Disruption of Proteostasis? https://www.fightaging.org/archives/2023/08/does-amyloid-%ce%b2-aggregation-cause-broad-disruption-of-proteostasis/ Researchers here speculate on the ability of insoluble amyloid-β aggregates to be broadly disruptive of the solubility of many other proteins, and thus disruptive to cell and tissue function. Is this important in aging? The evidence here shows the existence of the mechanism in a lower species, but that doesn't n...

A Senolytic Vaccine Targeting SAGP Reduces Pathology in a Mouse Model of Alzheimer ' s Disease
In this study, the research team created an Alzheimer's disease mouse model that mimics a human brain and simulates amyloid-beta-induced Alzheimer's disease pathology. To test the efficacy of the SAGP vaccine, the mice were treated with a control vaccine or the SAGP vaccine at two and four months old. Usually, people in the late stage of Alzheimer's lack anxiety, which means they are not aware of the things around them. The mice who received the vaccine had anxiety, which means that they were more cautious and more aware of things around them - a sign researcher say could indicate a lessening of the disease. In addition, s...

Is More Physician-Owned Hospitals the Solution to our Health Cost problem?
BY JEFF GOLDSMITH Robert Frost once said,  “Home is where, when you have to go there, they have to take you in.” Increasingly, in our struggling society, that place is your local full service community hospital.  During COVID, if it wasn’t your local hospital standing up testing sites, pumping out vaccinations and working double overtime helping patients breathe, we would have lost several hundred thousand more of our fellow Americans.   But it wasn’t just COVID where hospitals leaped into the breach.    As primary care physicians’ practices collapsed from documentation overburde...

Pulmonary Arterial Hypertension: Unraveling Its Impact On Heart And Lungs
Conclusion Navigating the complexities of Pulmonary Arterial Hypertension (PAH) might seem daunting. However, with the right knowledge and proactive approach, it’s possible to manage the condition and maintain a good quality of life. PAH, a unique type of high blood pressure affecting the arteries in the lungs, can put extra strain on the heart. Over time, this can lead to heart failure. The condition’s root cause may vary, from genetic factors to other health issues like heart defects, liver disease, or autoimmune diseases. Remember, sometimes the cause remains unknown, resulting in idiopathic pulmonary ...

In conclusion, the longevity-associated genotype of FLT1 may confer increased lifespan by protecting against mortality risk posed by hypertension. We suggest that FLT1 expression in individuals with longevity genotype boosts vascular endothelial resilience mechanisms to counteract hypertension-related stress in vital organs and tissues.

Not the Last of Them
BY KIM BELLARD I’m seeing two conflicting yet connected visions about the future. One is when journalist David Wallace-Wells says we might be in for “golden age for medicine,” with CRISPR and mRNA revolutionizing drug development. The second is the dystopian HBO hit “The Last of Us,” in which a fungal infection has turned much of the world’s population into zombie-like creatures.  The conflict is clear but the connection not so much. Mr. Wallace-Wells never mentions fungi in his article, but if we’re going to have a golden age of medicine, or if we want to avoid a global fungal outbreak, we better be p...

This study explored the association between different cooking fuel types and the risk of cancer and all-cause mortality among seniors constructing Cox regression models. Data were obtained by linking waves of 6, 7, and 8 of the Chinese Longitudinal Healthy Longevity Survey, which included a total of 7,269 participants who were 65 years old and over. Cooking fuels were categorized as either biomass, fossil, or clean fuels. And the effects of switching cooking fuels on death risk were also investigated using Cox regression models. The results indicate that, compared with the users of clean fuels, individuals using bio...

In conclusion, among Swedish middle-aged subjects, nearly two-thirds showed complete fatty degeneration of thymus on CT. Age-Related Dysfunction of Water Homeostasis https://www.fightaging.org/archives/2023/06/age-related-dysfunction-of-water-homeostasis/ Dehydration can be an issue in older people. As in every complex system in the body, the mechanisms by which hydration is regulated become dysfunctional with advancing age. Researchers here look at the brain region responsible for regulating some of the response to dehydration, cataloging altered gene expression in search of the more important mechani...

Senolytic Treatments as a Strategy to Improve Immune Function in Late Life
Senescent cells accumulate in tissues throughout the body with age. Cells become senescent constantly throughout life, largely by reaching the Hayflick limit on replication, but a small number due to potentially cancerous mutations, or other forms of damage and stress. Senescent cells are rapidly removed by the immune system in youth, keeping their numbers low, but the balance between creation and destruction is disrupted with aging. There is greater stress, but perhaps more importantly the immune system becomes less efficient, less able to clear senescent cells in a timely fashion. Since senescent cells actively secrete p...
