#Geroscience can't agree what #aging is

www.nature.com/articles/d41...

Even more problematic:

Each geroscientist is convinced that they themselves know what aging is

What do you think aging is?
— Loss of function?
— Accumulated damage?
— A disease?
— A continuation of development?
What is ageing? Even the field’s researchers can’t agree
Survey of scientists who study ageing finds no consensus on the fundamentals.

For all frailty levels, more healthy diet associates with
— reduced the risk of death
— increased expected lifespan
— dose dependent for diet healthiness

Fascinating proposal on how to treat #comatose pts

translational-medicine.biomedcentral.com/articles/10....

My favorite chapter title:
Coma patients still have functioning brains

We are learning that we should never give on comatose pts!

Reversing coma by senolytics and stem cells: the future is now - Journal of Translational Medicine
Global cerebral ischemia (GCI) caused by impaired blood flow to the brain—typically following cardiac arrest or traumatic brain injury—remains the leading cause of coma and disorders of consciousness (DoC). In certain cases, the recovery potential of these patients may be significantly underestimated. Historically, these patients were often given little hope for recovery, particularly due to longstanding, outdated dogmatic views such as the presumed absence of adult neurogenesis. However, recent advances suggest that we have been discounting ongoing mental activity in comatose patients; additionally, emerging evidence shows that some patients in coma retain the capacity for communication through non-traditional means. The authors believe that the exponential progress in the field and the increase of our understanding in neurophysiology, regenerative medicine, and the biology of cellular senescence now makes it plausible to initiate experimental interventions that offer a realistic chance of reversing disorders of consciousness. The proposed strategy involves a two-step therapeutic paradigm: first the use of senolytic approaches to remove senescent cells and reduce neuroinflammatory burden (“clear the debris”); second, stimulation of neural regeneration through stem cell therapies, combined with electrophysiologic/pharmacological stimulation. The authors propose, that this integrated approach offers a novel treatment paradigm to address the previously insurmountable challenge of coma reversal.

🔊TURN DOWN THE VOLUME

Californians don't want to hear commercials at a volume any louder than what they were previously enjoying their program at.

I just signed legislation enforcing this regulation across streaming platforms.

The ending of insurance subsidies didn’t happen as some accident that both parties need to fix; it was calculated policy crafted by and voted for by the GOP.

Long term, American voters will be better off knowing what the GOP vision for their healthcare is.

Let them own it.

Consider checking out what kinds of oxidative conditions can be generated by activated neutrophils

Through de-granulation & DNA net expulsion, they generate superoxides, peroxides & hypochlorites

Typically occurs in vasculature, but also in tissues

Republicans say the loss of enhanced tax credits are irrelevant?

Here's what happens to my #ObamaCare premium:

Currently $489/mo

When I sign up NEXT MONTH, my premium will be
$489 + $389 = $878/mo

That's an 80% increase!

Thank you Democrats for forcing a shut down until Republicans fix this!

Great point

And if the President were elected by ranked choice voting, they likely would install cabinet with their competitors to reinforce a more diverse coalition of supporters

We also currently have a Supreme Court problem that may need to be resolved by impeachments of justices

Donald Trump and his lapdog Republicans just shut down the federal government after refusing to protect Americans from an imminent spike in health insurance costs.

This is what the GOP stands for.

Excellent ideas in your substack

I prefer to characterize non-communicable diseases as “lifestyle transmitted diseases”

What are your thoughts on providing polyunsaturated fatty acid precursors via eye drops or topical skin administration?

Based on my VO2max, my 56-yo body can sprint as fast as the top 25% of men in their 20s & 30s!

Curiously, I had to change my calendar age from 56 to 36 to get my fitness app to report my recent VO2max values

There were 3 weeks of missing values when I began exceeding the max for my 50s age group!
