I don't get it. When I lived in Germany we could get Ranch dressing without any issue. Like Italian etc. Texan BBQ, NY Bagels, Chicago Pizza - ok. But Ranch Dressing (photo is no product endorsement)?
Some 🤬 blocked entire midtown East just to go to his taxed second home near Tiffany’s
Next, we tried it on Feraheme, a FDA-approved iron oxide nanodrug, tracked by [89]Zr PET. One 15-minute priming step with MPN nearly doubled tumor uptake at 6 hours and held onto a ~30% gain out to 24. Same principle, clinical-grade cargo.
So does vasodilation also mean more nanoparticle delivery? Give a 70 kDa dextran 15 minutes after MPN and the tumor takes up far more of it (~ 1.5×) and crucially, it goes also more into the core rather than piling up at the rim where most nanomedicine gets stranded.
And NitricO means vasodilation. Using optoacoustic imaging (RSOM), we showed tumor vessels widening in real time. The striking part: tumors responded more than three times as strongly as healthy skin. The messy, leaky vasculature we usually curse turned out to be the most responsive.
Meet MPN = methyl palmitate nanoparticles, made by Paolo's group. Simply an albumin shell wrapped around a lipid your own body already makes. Paolo's group had already shown they stun macrophage activity over a few hours (PMID 34617542). Our new paper is about something much faster.
Oddly it looks better here in NY than yesterday but it is only a bit lower in AQI, ~170. Freedom tower barely visible in the distance. Right today. Left comparison.
Do I really want to fly back THERE? First photo via Reuters. Second from my office April 2023. Smoke from Canadian wildfires.
Almost too hot to do this but it was worth it. Queluz National Palace in Lisboa
Happy Father’s s Day to all the dads and particularly my dad who I called first thing in the morning (he is +6h away). Him and me over 55 years ago. I am the one on the right 😘
I do not believe my eyes!! NoA apparently went out but of course our admin is out today.
