Only from 21 August 2007 so I wonder if there is any followup?

Two substances that occur naturally in the brain act to protect the
brain during a stroke. This is the conclusion of a dissertation
published at the Sahlgrenska Academy, and the discovery may lead to new
treatments for stroke patients.
Stroke is the result of an infarction, or bleeding, within the
brain, and it may lead to impaired movement, impaired sensation, and
difficulties in cognitive function and speech. Approximately 30,000
people are affected by stroke each year in Sweden, and it is the most
common cause of long-term dependence on care.
"Researchers all over the world are intensively searching for new
treatments. One interesting possibility is that of activating stem cells
in the damaged brain such that the brain can be repaired and regain its
function", says stem cell researcher Jonas Faijerson.
Stem cells are immature cells that reside in selected regions of the
adult brain. These cells can develop either into nerve cells or into
other cells that are important in the brain, such as astrocytes.
Astrocytes are the most abundant cell type in the brain, and they play
an important role when the brain is damaged.
The dissertation shows that activated astrocytes release substances that activate stem cells within the brain.
"We have shown that a very interesting hormone known as 'TRH' is
released in large amounts after a stroke, and that this hormone can not
only protect from damage but also lead to the activation of stem cells",
says Jonas Faijerson.
The stem cells also release survival factors to the surrounding
brain tissue when the brain is injured or diseased. The dissertation
describes the identification of a completely unknown survival factor,
which the researchers have named "pentinin".
"Pentinin protects brain cells from several of the effects that a
stroke causes. Both TRH and pentinin are interesting candidates for the
development of new treatment strategies for patients with stroke. It is
possible that these substances could be given in tablet form, as a drop,
or as a nasal spray, when a stroke is suspected", says Jonas Faijerson.
The research has been carried out at the Centre for Brain Repair and Rehabilitation at the Sahlgrenska Academy.
"This work was supervised by a revered friend and colleague, the late Peter Eriksson", says Jonas Faijerson.
Dissertation submitted for the degree of Ph. D. in Medicine at the
Sahlgrenska Academy, Institute of Neuroscience and Physiology, Section

Title of the dissertation: Neural Stem/Progenitor cells in the
Post-ischemic Environment: Proliferation, Differentiation and
Neuroprotection
The dissertation has been successfully defended.
Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 29,116 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
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.
