The nasal spray reduced markers of inflammation in hippocampal microglial cells.
A lot of things reduce inflammation. That is not "reversing ageing".
Of course, "reduces inflammation" doesn't headline very well...
1 - Find a marker correlated with aging across a large sample
2 - Find a medication or supplement that also alters that marker
3 - Do some before and after measurements of the marker with the supplement or medication, and claim that you have reversed aging. Rely on the fact that enough readers won’t look closely enough to wonder if the marker is a true independent variable that represents aging.
can you please share your methodology for detecting ai please?
That’s an AI tell. It may not be entirely LLM-generated, the various direct quotations help a lot, but there are touches that definitely feel like an LLM had a hand here.
"Over decades, it doesn’t just wear down, it also starts to run hot." "... the therapy didn’t just clear brain fog, it physically improved the brain’s ability to process and store information."
The quotes as well: "'... Not just living longer, but living smarter and healthier,' Shetty said." "'We aren’t just trying to understand the biological mechanisms, we are translating and developing our findings into real-world therapies that could make a difference,' Shetty said."
Whining by humans claiming AI? Predictable. Probable. Indeed LLM "complete the sentence" predictable.
It's also an actually interesting question.
It's one thing to find some things hard to follow, it's another to be proud of it.
If we could breed or treat rodents to live longer, we could keep low-resource pets without as much loss.
Considering the grand total of experiments we've ran on the little guys, I'm kinda surprised we haven't bred Mousezilla yet
Intranasal Human NSC-Derived EVs Therapy Can Restrain Inflammatory Microglial Transcriptome, and NLRP3 and cGAS-STING Signalling, in Aged Hippocampus[1].
Abstract:
> Neuroinflammaging, a moderate, chronic, and sterile inflammation in the hippocampus, contributes to age-related cognitive decline. Neuroinflammaging comprises the activation of the nucleotide-binding domain, leucine-rich repeat family, and pyrin domain-containing 3 (NLRP3) inflammasomes, and the cyclic GMP-AMP synthase (cGAS)-stimulator of interferon genes (STING) pathway that triggers type 1 interferon (IFN-1) signalling. Studies have shown that extracellular vesicles from human induced pluripotent stem cell-derived neural stem cells (hiPSC-NSC-EVs) contain therapeutic miRNAs that can alleviate neuroinflammation. Therefore, this study examined the effects of late middle-aged (18-month-old) male and female C57BL6/J mice receiving two intranasal doses of hiPSC-NSC-EVs on neuroinflammaging in the hippocampus at 20.5 months of age. Compared with animals receiving vehicle treatment, the hippocampus of animals receiving hiPSC-NSC-EVs exhibited reductions in astrocyte hypertrophy, microglial clusters, and oxidative stress, along with elevated expression of antioxidant proteins and genes that maintain mitochondrial respiratory chain integrity. Moreover, hiPSC-NSC-EVs therapy decreased the levels of various proteins involved in the activation of the NLRP3 inflammasome, p38/mitogen-activated protein kinase, cGAS-STING-IFN-1, and Janus kinase and signal transducer and activator of transcription signalling pathways. Furthermore, in vitro assays using genetically engineered RAW cells and hiPSC-NSC-EVs, with or without targeted depletion of specific miRNAs, demonstrated that miRNA-30e-3p and miRNA-181a-5p, both present in hiPSC-NSC-EVs, can significantly inhibit the activation of the NLRP3 inflammasome and the STING pathway, respectively. Additionally, single-cell RNA sequencing conducted 7 days post-treatment revealed that hiPSC-NSC-EVs induce widespread transcriptomic changes in microglia, including increased expression of numerous genes that enhance oxidative phosphorylation and reduced expression of abundant genes that drive multiple proinflammatory signalling pathways. These changes mediated by hiPSC-NSC-EVs were also associated with improved cognitive and memory function. Thus, intranasal hiPSC-NSC-EVs therapy in late middle age can effectively diminish proinflammatory microglial transcriptome and signalling cascades that drive neuroinflammaging in the hippocampus, contributing to better brain function in old age.

NAC is one of the only known treatments for trichotillomania, a under discussed but common condition that causes people to uncontrollably pull their hair out.
NAC has also been studied to reduce nicotine and alchohol cravings as well.

Most cultures find it taboo to donate their beloved family members bodies for scientific dissection. Thus, people get ingrained "[bigotry] with extra steps" similar to phrenology proponents.
