Engineered ETS1‐Nanoconjugate Restores Immune Homeostasis through Dual Immune‐Vascular Modulation in Relapsing and Progressive Multiple Sclerosis

Advanced Healthcare Materials, EarlyView.
The biomimetic nanoplatform IMNP (ETS1 pDNA/PBAE@ITP‐MM) undergoes targeted disassembly at inflammatory vascular sites to release the ETS1 plasmid (pETS1). This release initiates a cascade of effects that inhibit pathogenic pathways and support immune homeostasis. (Abbreviations: EndMT, endothelial‐to‐mesenchymal transition; EC, endothelial cell; TC, T

Historical development of traffic signs

Promet (Zagreb), 1998
The road regulations and traffic signs, as we know them today, are not older than a hundred years. When the first motor vehicles appeared on the roads, passing the state borders ever more frequently and easily, and that was at the beginning of the 20th century the need arouse to determine international regulations that would harmonise the information ...
