    Aging Of A 53 YO Male After 25yrs of Dutasteride 35yrs Oral Steroids + No Testosterone Or DHT

    On top of suppressing his natural testosterone production to nothing until age 51 by taking oral steroids, he suppressed his dht to about zero by taking a full dose of dutasteride. He added 125mg of testosterone at age 51 and used to take aromatase inhibitors when he was taking growth hormone...

    Major depression likely driven by mitochondrial deterioration/dysfunction

    This the latest study demonstrating that not only are various chronic diseases and aging essentially the same process, but that this process is fundamentally bioenergetic in nature. Namely, dysfunctional mitochondria, leading to low OXPHOS, is the direct cause of many physiological and "mental"...

    MTOR Increases With Aging/Sarcopenia, (Partial) Inhibition Restores Muscle Mass

    This was a nice experiment which upsets the naive axis of anabolism and catabolism commonly-associated with the mTOR (mammalian target of rapamycin). Its activation is not sufficient to maintain muscle mass, and partially inhibiting it can unexpectedly restore muscle. Common medical advice is...

    Higher protein, sugar, and vitamin E consumption beneficial for health/aging

    I would say right from the start that there are obviously a very large number of dietary components that can have beneficial effect on our health. The study below cannot possibly look at all of them, but from the ones it examined those three (3) variables the title mentions gave the most benefit...

    Being Sad and Lonely Accelerates Aging More Than Smoking

    The title is the same as the one of the popular press article. And since feelings of sadness and loneliness are primarily caused by elevated serotonin, we can add premature aging to the list of "benefits" serotonin offers. The findings of this study probably explain a great deal of the premature...

    Negative childhood experiences accelerate aging/disease in humans

    I am posting this study mostly as a counterexample to all the drivel coming out of gerontology research circles. Namely, the dogma is that biological aging is overwhelmingly influenced/determined by genes and cannot really be retarded (pun intended) or accelerated by the environment. This dogma...

    ...whether you are 18 or 80. Yes, I know it is hard to believe this statement but that is the conclusion of the study after examining the link between lifestyle (and environment) and cognitive function in a group of people with ages spanning the 18-89 years interval. The conclusion of the study...

    No evidence for rate-of-living theory of aging

    Just a quick post, since this topic dominates anti-aging research - i.e. despite lack of concrete evidence for it, mainstream research (and finding agencies) continue to claim that longevity is tied to metabolism, but in an inverse relationship. The study below is on turtles - one of the longest...

    "Endurance" exercise ages the vascular system of males by more than a decade

    A very interesting study, though I don't really agree with its findings that while "endurance" (in this case running) exercise damages male vascular system it is beneficial for the female one. The majority of intervention studies that looked at both sexes, across all age groups found that...

    Vitamin D supplementation is associated with slower epigenetic aging

    Adverse effects of low vitamin D level on mortality and morbidity are controversially discussed. Especially older people are at risk for vitamin D deficiency and therefore exposed to its potentially harmful consequences. A way of measuring differences in the biological age is through DNA...

    Hypogonadism in older males due to low OXPHOS

    I suspect many readers will simply say "duh!", but believe or not the origin of age-related hypogonadism in males is still considered unknown. Most endocrinologists have discovered experimentally that treating their patients with SERM or AI drugs restores androgens to youthful levels, but the...

    Age-related steroid deficiency may be treatable with niacinamide

    The study is actually about eye health, and the effects androgens play in it. However, the findings are not limited to the eyes and are in fact applicable for any other tissue/organ experiencing a decline in steroidogenesis with advancing age, which is basically all of them. As such, I am...

    Fasting causes aging by energy depletion, vitamin B2 can stop it

    Well, if this title does not rile up the fasting crowd, I don't know what will:-) Aside from that controversy, it is actually a great study that not only suggests a dirt cheap and widely available option for retarding aging, but once again demonstrates that stress (e.g. fasting) directly causes...

    Hypercapnia-inducible factor: a hypothesis | Aging and longevity

    Abstract Cells and tissues sense and respond to hypercapnia by global activation or down-regulation of hundreds of genes and switching on/off a number of signaling and metabolic pathways. We hypothesize for the first time that such complex rearrangements are hardly possible without subtle...
