In conclusion, iMSC-sEVs could rejuvenate the senescence of NPCs and attenuate the development of IVDD.
Cell Signaling via Exosomes in the Development of Vascular Calcification
https://www.fightaging.org/archives/2021/05/cell-signaling-via-exosomes-in-the-development-of-vascular-calcification/
Vascular calcification is a feature of aging, a process in which cells in the blood vessel wall take on inappropriate identities and activities that are more appropriate to bone tissue. Evidence of recent years implicates chronic inflammation and the presence of senescent cells in this process. Senescent cells caus...

In conclusion, we showed that addition of resistance exercise training, but not dietary EAAs, to the myostatin inhibition further increased muscle mass through the attenuation of muscle protein breakdown with proportionate improvements in muscle strength. Interestingly, addition of dietary EAAs to the myostatin inhibition with or without resistance exercise training improved muscle quality. Thus, dissection of the underlying mechanisms behind the combined positive effect of dietary EAAs and resistance exercise training on muscle mass and quality can shed light on the discovery of effective therapeutics against muscle wasti...

On Balance, Vegetarians Exhibit Better Biomarkers than Non-Vegetarians
There is a fair amount of epidemiological data to suggest that vegetarians have, on balance, better long-term health prospects than people who consume meat. The usual caveats apply, in that vegetarianism in many wealthier study populations is correlated with a range of other potentially relevant line items, such as education, wealth, and better lifestyle choices. Further, the average vegetarian may well be mildly calorie restricted in comparison to the average meat eater, and that may be enough in and of itself to explain health effects. Other suggested contributing factors include dietary advanced glycation end-products, ...

Epistemology VI: Epidemiology
Epidemiology originally largely meant studying how infectious diseases spread, and that ' s still a major concern of epidemiologists. However, it also includes the study of any and every environmental or behavioral factor affecting human health. For example, the finding that smoking tobacco causes lung cancer (not to mention a bazillion other diseases) is an epidemiological finding. Epidemiology is largely an observational science, given the ethical prohibition against exposing humans to potentially hazardous conditions for experimental purposes. That ' s not to say it hasn ' t been done, with the victims being ...

5 inflammation-fighting food swaps
Inflammation: if you follow health news, you probably hear about it often. When is inflammation helpful? How can it be harmful? What steps can you take to tone it down?
What is inflammation and how does it affect your body?
If you’re not familiar with the term, inflammation refers to an immune system reaction to an infection or injury. In those instances, inflammation is a beneficial sign that your body is fighting to repair itself by sending in an army of healing white blood cells. As the injury heals or the illness is brought under control, inflammation subsides. You’ve probably seen this happen with a minor ankle sp...

Foreword to Wheat Belly Revised & Expanded Edition
An excerpt from the Wheat Belly Revised & Expanded Edition:
Have you ever come home from the grocery store with a fresh container of milk, opened it and immediately realized that it was bad—sour-smelling, curdled, unfit to drink?
Feed it to the cat? Probably not. Lighten your coffee? I don’t think so. Pour it down the sink—yeah, that’s the ticket. Or maybe go back to the store with some of the curdled remains and ask for your money back.
That is what your reaction to conventional dietary advice should be. You should wrinkle your nose at the bad smell that emanates from advice that creates an astonish...

Health effects of partial hydrogenation of vegetable oils
Partially hydrogenated vegetable oils contain trans fatty acids which are different from the natural fatty acids in vegetable oils and animal fat [1]. Fatty acids in partially hydrogenated vegetable oils are 14 cis and trans isomers of octadecenoic and octadecadienoic acids that are formed during hydrogenation. Trans fatty acids cause inflammation and calcification of arterial walls. They also inhibit cyclooxygenase needed for conversion of arachidonic acid to prostacyclin, a compound beneficial for the vascular tree. There are reformulations of hydrogenated fat containing the essential fatty acid linoleic acid which get...

In this study, the research team designed a way to identify small molecules that improve the function of ABCA1 in the body while avoiding unwanted effects to the liver. The researchers honed in on a specific small molecule, CL2-57, due to its ability to stimulate ABCA1 activity with positive effects on liver and plasma triglycerides. The use of this compound showed improved glucose tolerance and insulin sensitivity, as well as reduced weight gain, among other beneficial effects.

Naked Mole Rats Employ Cholesterol Metabolism to Enable Cells to Resist the Senescent State
Naked mole-rats exhibit an unusually longevity, with a life span something like nine times as long as that of equivalently sized mammals. They are also highly resistant to cancer. This makes them an attractive subject for research into ways to treat aging and age-related disease. No one mechanism will be the exclusive source of these traits in the naked mole-rat, but it is interesting to look at the way in which cellular senescence is different in this species.
Senescent cell accumulation takes place in tissues throughout the body with advancing age, and in other mammals those senescent cells cause harm via their se...

James Peyer of Cambrian Biopharma on Defining Aging as a Disease
James Peyer was involved in the aging-focused fund Apollo Ventures before he moved on to the more recent venture industry initiative that evolved into Cambrian Biopharma. Cambrian is arguably even more focused on creating new biotech startups to treat aging, rather than investing in existing companies, than is the case for Apollo. Many venture capitalists are coming to the conclusion that the pace at which new biotech companies in this space are arising is too slow to provide sufficient opportunities for the capital that could be harnessed to produced progress. That pace must thus be accelerated.
Peyer is a regular ...

Near-Infrared Hyperspectral Imaging Detects Liver Fat Content

Fight Aging! Newsletter, March 22nd 2021
This article expresses sentiments regarding medical technology and human longevity that we'd all like to see more of in the mainstream media. At some point, it will come to be seen by the average person as basically sensible to work towards minimizing the tide of suffering and death caused aging and age-related disease. It has been, in hindsight, a strange thing to live in a world in which most people were reflexively opposed to that goal.
Death and aging constitute a mystery. Some of us die more quickly. We often ask about it as children, deny it in youth, and reluctantly come to accept it as adults. Aging is uni...

Tsimane and Moseten Hunter-Gatherers Exhibit Minimal Levels of Atrial Fibrillation

Epidemiological data for the Tsimane and Moseten populations in Bolivia shows that they suffer very little cardiovascular disease in later life, despite a presumably greater lifetime burden of infectious disease (and consequent inflammation) than is the case for people i...

This study may have important implications for preventing cell senescence and aging-induced tendinopathy, as well as for the selection of novel therapeutic targets of chronic tendon diseases.
Our results showed that the treatment of bleomycin, a DNA damaging agent, induced rat patellar TSC (PTSC) cellular senescence. The senescence was characterized by an increase in the senescence-associated β-galactosidase activity, as well as senescence-associated changes in cell morphology. On the other hand, rapamycin could extend lifespan in multiple species, including yeast, fruit flies, and mice, by decelerating DNA damage ...
