Awesome progress but do not forget that TP53 mutations are likely a biomarker for patients who stand the most to gain from vitamin D replacement therapy and it is far less toxic and expensive.

Your gut isn’t just digesting food… It’s running a biochemical factory that keeps you alive.
Most people think the colon is just “where waste goes.”
But this illustration shows something more:
Your colon is one of the most underrated metabolic organs in the entire body.
Inside this 5-foot stretch of tubing, billions of bacteria are:
🔥 Creating vitamins
🔥 Producing short-chain fatty acids (the fuel your colon cells run on)
🔥 Detoxifying harmful compounds
🔥 Breaking down proteins into neurotransmitter precursors
🔥 Regulating your immune system
🔥 Deciding whether you feel inflamed, bloated, focused, or foggy
And all of it is happening silently, every hour of every day.
Looking closer at what this one diagram reveals:
🔸 Fiber → SCFAs (butyrate, acetate, propionate)
These molecules lower inflammation, feed colon cells, improve insulin sensitivity, and even influence mood.
🔸 Protein → amino acids → neurotransmitter precursors
Yes, your gut bacteria help shape serotonin, dopamine, and even histamine levels.
🔸 Your colon detoxifies more than your liver gets credit for.
Phenols, ammonia, indoles, cresol, skatole. Your microbes help neutralize them before they ever hit your bloodstream.
🔸 Gas, pH changes, mucus secretion, metal excretion, nutrient salvage; it all happens here.
Your colon saves water, electrolytes, energy, and even rescues calories you would otherwise lose.
🔸 The final 135 grams of stool are only a fraction of the metabolic work happening behind the scenes.
This is why gut health affects EVERYTHING: digestion, immunity, mental clarity, inflammation, skin, sleep, metabolism; all of it.
Your gut isn’t a waste pipe.
It’s an ecosystem, a chemical lab, and a second brain whispering instructions to the rest of your body.

First snowfall of winter in Chicago, so no better time to post a public service announcement/reminder: Do you know your vitamin D25 level? Did you know over the counter D3 leads to production of LL37 which lyses/destroys RSV, influenza, and yes all coronaviruses including COVID19. Let's bring scientific knowledge into action and make America Healthy Again #MAHA. Vitamin D Deficiency in Cancer Care: An Urgent Call to Action integrativeonc.blog/2025/07/…
For the love of God, never sign up for Meridian insurance. They just denied neulasta for high risk chemotherapy saying to use 7 day neupogen instead, then denied that 7 day neupogen as well, and then required a patient to sign an 'authorization form' to let me (her oncologist) to appeal the denial and only allows this patient form via fax, as if we all have fax machines still. It's two weeks after her chemotherapy and Meridian is doing their absolute best to not get it covered/delivered. Doctors and patients alike just want less obtuse insurance approval protocols designed to frustrate care and worsen quality of life for Americans #MAHA @RobertKennedyJr
Not to say doctors are immune to conflict of interest, but come on man...politicians and athletes take COI to a level of professional pride these days.
The FBI is holding a press conference right now on the details around this morning's sports gambling bust.
Here are some of the highlights:
1. Current and former NBA players and coaches Chauncey Billups, Terry Rozier, and Damon Jones have been arrested.
2. This was an illegal gambling and sports rigging operation that spanned years across 11 states. In total, 30 individuals have been arrested (13 mafia members).
3. The case involves La Cosa Nostra (the Italian mafia).
4. Charges include illegal gambling, wire fraud, and extortion.
5. There are two separate indictments. The first involves six defendants accused of participating in a sports corruption scheme that exploited insider information involving NBA players and teams. The defendants leveraged their connections to place prop bets based on confidential insider information, winning tens of thousands of dollars per bet.
The second indictment involves 31 defendants charged with participating in a nationwide scheme to rig illegal poker games. The FBI says they used high-tech cheating technology to steal millions of dollars from victims in underground poker games that were secretly fixed.
6. The two cases are separate, but there are three overlapping defendants, including former NBA player and coach Damon Jones.
7. The FBI says that NBA player Terry Rozier told the defendants that he was going to leave a game early on March 23, 2023, with an injury. The defendants then placed more than $200,000 of wagers on the unders for his prop bets, with Rozier leaving the game after nine minutes. Those bets paid out tens of thousands of dollars in profits, and the defendants and Rozier counted the money at his house.
8 The FBI says that former Raptors player Jontay Porter was threatened to participate in the sports gambling scheme because of his gambling debts.
9. Teams that were bet on during the sports gambling scheme include the Charlotte Hornets, Portland Trail Blazers, Los Angeles Lakers, and the Toronto Raptors.
10. The rigged poker games occurred in the Hamptons, Miami, Las Vegas, and Manhattan.
11. The poker scheme targeted victims who were lured to participate in rigged poker games by the chance to play alongside former professional athletes. These athletes included Chauncey Billups and Damon Jones.
12. The FBI says that the defendants utilized altered shuffling machines to read the cards in the deck and then relayed that information to an off-site operator. The offsite operator — known as the "quarterback" — then sent that information to someone at the table.
13. The FBI also says that the defendants utilized other cheating technologies, including poker chip trays that read cards through hidden cameras, special contact lenses and glasses that could read marked cards, and x-ray poker tables that could read cards face down.
14. The FBI says that the defendants robbed a victim at gunpoint to acquire a rigged shuffling machine.
15. The sports gambling investigation is called "Operation Nothing But Net," while the poker investigation is called "Operation Royal Flush."
16. The FBI has been working on this investigation for four years, with victims losing at least $7 million.
17. One specific victim lost at least $1.8 million.
18. The FBI reviewed thousands of hours of video evidence and executed more than two dozen search warrants.
These are just accusations at this point. I am just pointing out details from the FBI's investigation.

“Environment” = not enough sunshine or outdoor activity creating a unique imbalance of vitamin D particularly in African Americans. >90% of African Americans are Vitamin D deficient in the US! And most doctors do not know how to replace a severe deficiency - Which is why i published a vitamin D chapter for free online at integrativeonc.blog

"Field-mediated bioelectric basis of morphogenetic prepatterning"
#morphogenesis #bioelectricity #fields
"Intercellular bioelectric communication plays an important role in morphogenesis, often modeled using localized non-neural networks generating spatial patterns of membrane potential (Vmem). Here, we find that the electrostatic field contributes to this process, via a synergetics (à la Haken)-based mechanism, by enhancing the complexity of Vmem patterns through a coarse-grained projection. We leverage this property of the field to automatically optimize transient signals from a symmetry-breaking organizer region in the boundary of the tissue to mold Vmem patterns in the bulk. Two models optimized in this way exhibit contrasting “mosaic” and “stigmergic” pattern-coding strategies, depending on their field sensitivity strengths. Interestingly, the stigmergic model recapitulates the qualitative developmental sequence of the bioelectric craniofacial prepattern observed in frog embryos. These results highlight the potential of the electric field both as a facilitator of collective patterning and as a macroscale interventional target for applications in regenerative medicine and bioengineering."
