AY '26-'27 Goals

  • Submit a manuscript for publication
    • Meet w/ Nina
    • Identify two journals (plan A and plan B) to submit Brandon's study to. Understand their submission requirements. Write up the introduction for the study in LaTeX, formatted and tailored appropriately for each journal.
  • Submit RISE 1 application
    • Narrow down research directions and goals
    • Literature review to refine research aims
    • Identify mentors and institutional resources
  • Identify additional funding sources and apply
  • Start recruiting a research team

10/2

  • E-mailed slides to Nina and followed up on study
  • Texted Brandon about which journals to submit to. 1st choice: A&A, 2nd choice: Journal for Obstetric Anesthesia
  • Does TIVA prevent cancer recurrence? Head of Huntsman anesthesia did a cancer anesthesia fellowship and researched this a bit. Though he's now burned out on research, he's the guy to talk to about what's already been done or not.
  • Hamilton and I talked about why ketamine causes lasting changes in the brain long after the drug is gone. Is it a change to a gap junction network? Is it anti-inflammatory circulating EVs?. There are three papers on MedLine related to ketamine and EVs, none of which look (anti-)inflammatory molecules. Do circulating EVs after propofol anesthetic also contain the inflammatory cytokines that are seen after isoflurane?

Mechanisms of Anesthesia

  • High-throughput screen of anesthetics (and anesthetic reversal agents) in C.elegans. I could work in parallel in a different organism (yeast? bacteria? plants? neuronal explants?).
  • Based on 30 years of in vitro studies (n>300), most anesthetics exhibit similar potency across a range of receptors. Most receptors are non-selective for ligands. What this paper addresses but doesn't answer is whether the receptors are present at the correct locations and necessary to the anesthetic behavioral response.
  • Some anesthetics (ketamine, dexmedetomidine, etomidate, benzos) are fairly selective, but are rarely used as sole anesthetics.
  • 2026 A&A paper argues that classifying anesthetics as, say, GABAergic vs. NMDAergic is misleading. Propofol for instance actually has higher potency at the α4β2 nAChR and HCN1 receptors than at the "classic" GABAAR receptor.
  • What if you found pharmacological inhibitors that were receptor specific and gave them together with "promiscuous" anesthetics. For instance, is propofol equally effective when given with a specific HCN1 receptor inhibitor? What about a GABAAR inhibitor? Could you do optogenetic location-specific receptor knockdowns?
  • Hamilton has a gap junction (network of gap junctions?) and some specific neurons that he think are a conserved mechanism of anesthesia. He wants to test this by doing a screen of a bunch of different anesthetics in WT and KO worms with a behavioral screening assay. He has a behavior rig that basically automatically records swimming speed. He wants to look for the EC50 of various anesthetics and see if that number is shifted with KO or KD of different gap junctions.
  • Worms natively have a blue-light rhodopsin that triggers an aversion response where they turn around and go the opposite direction.
  • Next call 10/14.

CLAN

  • Definitely want to continue the alpha entrainment analgesia study.
    • Successfully entrain alpha. What were we doing wrong? Is there anything in the literature that can guide a protocol modification?
    • Can I somehow incorporate withdrawal thresholds?
    • Make it multi-center
    • Is alpha dropout selective for certain types of pain?
    • Power analysis based on pilot study
    • Systematic review and meta analysis
  • What are the EEG effects of benzos, opioids, precedex, and their respective reversal agents, caffeine, methylphenidate, and methohexital? In MedLine, combine each agent with the search term electroencephalography and add limits for Adults, Humans, and English. Which drugs are most target selective? What are their EEG effects?
    • Yohimbine = 9
    • Naloxone = 28
    • Methylphenidate = 68
    • Methohexital = 80
    • Flumazenil = 94
    • Caffeine = 138

CO2

  • Does permissive hypercapnia improve hemodynamic stability, improve oxygen delivery to tissues, deepen anesthesia, and speed recovery?

Depression

  • Do ketamine, TIVA w/ propofol, TIVA w/ remimazolam, psychedelics, or burst suppression modulate the post-operative risk of depression?
