An Epigenetic Fate Converter Based on Nuclei‐Targeting Lipid Nanoparticles Drives Neuronal Programming of Stem Cells for Spinal Cord Repair

Advanced Functional Materials, EarlyView.
Schematic illustration of LNP‐MPG nuclei‐targeting delivery of HMW‐FGF2 promoting histone acetylation to regulate the fate of DPSCs and treat spinal cord injury. LNPs components include pHMW‐FGF2 plasmid, DSPC, Dlin‐MC3‐DMA, cholesterol, and PEG2000, and are modified with MPG to form HMW‐FGF2@LNP‐MPG (HLM). HLM nuclei‐targets DPSCs to deliver HMW‐FGF2,

Analysis of perfusion index parameter [PDF]

, 2018
Pulzní oxymetrie je neinvazivní optická diagnostická metoda, pomocí které lze měřit saturaci krve kyslíkem ale i jiné veličiny. Jedním z parametrů, který lze měřit pulzním oxymetrem, je perfuzní index.
