Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Nanoparticles help track human heart muscle cells in mice in Stanford study

And if our stem cell researchers don't do the same thing to track where they go in the brain, their research is totally useless.

This beautiful image shows human heart muscle cells called cardiomyocytes that have been derived from embryonic stem cells and then reintroduced into the beating heart of a living mouse. Understanding where these reintroduced cells go in the heart, and what they do when they get there, is a critically important step toward using the cells to repair heart disease.
Here Stanford Cardiovascular Institute instructor Xulei Qin, PhD, and cardiologist Joseph C. Wu, MD, PhD, along with radiologist Heike Daldrup-Link used a new technique called photoacoustic imaging to visualize semiconducting polymer nanoparticles they’ve latched onto the cardiomyocytes (whose nuclei are shown in blue) like microscopic ankle bracelets. The nanoparticles, indicated in the photo in red, absorb laser light and emit acoustic signals that be used to quickly and accurately track the cells’ location with unprecedented sensitivity and resolution — even when they are buried by several millimeters of tissue. They published their results earlier this month in Advanced Functional Materials.
As Wu explained to me in an email:
This technique provides a much better way to follow how the cells integrate in small animal models because these nanoparticles have strong photoacoustic signals and specific spectral features to sensitively detect and distinguish a small number of labeled cardiomyocytes from native heart tissues.
Previously: A new label will allow physicians to pinpoint locations of bacterial infections,  Nano-hitchhikers ride stem cells into heart, let researchers watch in real time and weeks later and Stem cells create faithful replicas of native tissue, according to Stanford study
