In this study, we found that DMC reduced the SASP level in senescent cells. Furthermore, senescent cells enter irreversible cell cycle arrest, which involves the activation of p53/p21 and Rb/p16. In this study we found that the expression levels of p21 and p16 were decreased after DMC treatment. The downregulation of p21 may be attributed to the decrease of p53. In this study, we found that the mRNA level of p53 was reduced after DMC treatment. Ferroptosis is an iron-dependent cell death process, which is accompanied by iron accumulation. Our previous study reported an important role of FECH, an enzyme inserts ferro...

Flagellin Immunization Modestly Extends Life Span After Late-Life Administration in Mice
The immune system recognizes flagellin as foreign. Flagellin is the protein found in flagellae, the whip-like structures that bacteria use to move around. Attacking and destroying these bacteria is very much a part of the immune system's portfolio of normal activities. Thus immunization with flagellin provokes the immune system into greater activity and responsiveness in the short term, and it has been tested in humans as a vaccine adjuvant, intended to make the immune system respond more effectively to the vaccine delivered alongside flagellin. Interestingly, flagellin immunization also makes the immune system clear out h...

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 c...

More Evidence for Vaccination to Reduce Alzheimer's Disease Risk
There is good evidence for the various forms of later life vaccination, such as for herpes zoster or influenza, to reduce the risk of later suffering Alzheimer's disease. One possibility is that people who take the time to obtain a vaccine tend to take better care of their health across the board. Another possibility is that vaccination produces a trained immunity effect that dampens age-related inflammation for a sustained period of time. It may also be the case that suffering from influenza, pneumonia, or similar infectious diseases causes sufficient additional inflammation to move the odds on suffering later neurodegene...

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 this study, we used a Drosophila model to understand the role of the dec2P384R mutation on animal health and elucidate the mechanisms driving these physiological changes. We found that the expression of the mammalian dec2P384R transgene in fly sleep neurons was sufficient to mimic the short sleep phenotype observed in mammals. Remarkably, dec2P384Rmutants lived significantly longer with improved health despite sleeping less. In particular, dec2P384R mutants were more stress resistant and displayed improved mitochondrial fitness in flight muscles. Differential gene expression analyses went on to reveal several altered tr...

Myocarditis update from Sweden
BY ANISH KOKA The COVID19/vaccine myocarditis debate continues in large part because our public health institutions are grossly mischaracterizing the risks and benefits of vaccines to young people. A snapshot of what the establishment says as it relates to the particular area of concern: college vaccine mandates: Dr. Arthur Reingold, an epidemiology professor at UC-Berkeley, notes that UC also requires immunizations for measles and chickenpox, and people still are dying from COVID at rates that exceed those for influenza. As of Feb. 1, there were more than 400 COVID deaths a day across the U.S. “The arg...

This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed. The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

Viral Infection in Middle Age Correlates with Later Dementia Risk
A range of evidence suggests that persistent viral infection contributes to the risk of suffering neurodegenerative conditions such as Alzheimer's disease. This may be due to mechanisms relating to amyloid-β accumulation, in its role as an anti-microbial peptide, a part of the innate immune system. It may have more to do with lasting chronic inflammation subsequent to infection. Researchers here note another addition to the epidemiological data on this topic, in this case linking severe infections requiring hospitalization with later dementia risk. The effect sizes here are large and last for a long time following infecti...

The college football fans that beat COVID and the experts that couldn ’t
BY ANISH KOKA The COVID pandemic was supposed to herald the end of the idea that a smaller government is a better government. The experts who desperately seek to be in charge of a sprawling bureaucratic state told us that it was only a powerful central authority that could do what was needed to safeguard individual liberties at a time when a highly contagious respiratory virus was spreading across the globe. New Zealand may have imposed draconian policies that did not even allow its own citizens to return, but scenes of cheering unmasked New Zealanders stood in sharp contrast to empty seats in American stadiums when ...

Conclusion Use of the Khavinson peptides and melatonin in combination in this way, at this dose, negatively impacts the thymus, producing a reduction in active tissue and increase in atrophy to fatty tissue. The degree to which this atrophy occurred is greater than one would expect to take place over nine months of aging at this stage of life. Why did this outcome occur, given the animal studies showing thymic regrowth, and the studies showing reduced later life mortality following use of thymogen? We can only speculate. Firstly, the dose makes the poison, and the dosing here may have been too high, too frequ...

Influenza Vaccination Correlates with Modestly Lower Risk of Stroke
Following on from a recent study that suggested undergoing yearly vaccination for influenza can greatly reduce Alzheimer's risk, researchers here show that influenza vaccination correlates with a lower risk of stroke. The mechanisms of interest behind both of these correlations seem likely to revolve around chronic inflammation, an important factor in both the growth of atherosclerotic plaques in blood vessels and the onset and progression of neurodegenerative conditions. Firstly, suffering influenza is an inflammatory event, and the vaccine lowers the incidence and severity of that outcome. Secondly vaccination of this so...
