Inquiring minds demand to know. Would this help survivors during the first week? We have no one to ask this of because our stroke associations are not the repository of any stroke strategy.
We are F*cking screwed because we have no one to follow up on any promising leads from research. A
great stroke association would do translational research and create stroke protocols for promising ideas. In a perfect world it would do that, but not here.

Retinoic acid (RA) plays an important role in the commitment,
maturation
and survival of neural cells. Recently, RA was pointed as a
therapeutic option for some neurodegenerative diseases, including
Parkinson's disease (PD). The administration of RA has been defying, and
in this sense we have previously developed novel RA-loaded polymeric
nanoparticles (RA-NPs) that ensure the efficient intracellular transport
and controlled release of RA. Herein, we show that nanoformulation as
an efficient neuroprotective effect on dopaminergic (DA) neurons in the
1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP) induced mouse
model for PD. The results showed that the RA-NPs administration induced a
significant reduction of DA neuron loss in the substantia nigra (SN) as
well as their neuronal fiber/axonal innervations in the striatum.
Furthermore, we observed an increase in the expression levels of the
transcription factors Pitx3 and Nurr1 induced by RA-NPs, showing its
supportive effect on the development and functional maintenance of DA
neurons in PD. This is the first study showing that RA-NPs can be an
innovative strategy to halt the progression of PD pathogenesis,
suggesting that this nanoformulation could be of particular interest for
the development of new approaches for PD therapeutics.
