Justice-for-All? Amy Price PhD

Illusory statements and human error can set context that overthrows justice. In my life I have seen the guilty walk and the innocent executed based on what passes for science. Probability and statistics are used as weapons promoting authority over individuals unlearned in the field with little regard for the human carnage and heartbreak that follows.
Want to see the power of optical illusions? They are not as powerful as those that can be created by illusory context. Illusions are the gap between perception and processing, they operate in all senses and we are all susceptible
I recently enjoyed a forensics experiment where we were given a cursory fingerprinting class and then were given prints to compare for accuracy. There is a commonly held 16 points of accuracy that until recently was used to determine probability...plenty of room for error, even though Sir Francis Galton says mathematically the chances of identical fingerprints are 60 billion +.
I was interested in the case of a Scottish police officer who because of mistaken identity, lost her job, reputation and was driven to near bankruptcy because her accusers needed to be right more that they cared about justice. The officer later settled for 1.75 million pounds without the agency admitting guilt. I shudder to think how little she would have recovered for personal use after all the 3 ds (denial,delay and) were exercised. In fact those that brought faulty evidence were later exonerated by the department. Of course a 273 page document explaining how to do it better was produced but I doubt the officer gets royalties...
Dr Itiel Dror shared in an interview with the BBC how he engaged forensic specialists in a study where he linked context with perception during fingerprint analysis. There was a large error rate. The video and study is worth viewing. He shows how the stage can be set for seasoned professionals to make errors
In another case a Lawyer was held in Oregon as a terror suspect, his life was derailed and finally with the words "regrettably there was an error" he was released. I doubt that fixed much for him or bought him back time that was stolen in the prime of his life. He will likely be remembered as the 'Terror Suspect" rather than for other contributions he makes.
In the experiment most of us correctly identified these prints as not matching his. What went wrong? Try it for yourself

What is the take home message? Before you render judgement or accusation really listen with a mind to hear. Your 'facts' may be clouded by context and false perception. At any rate we can choose a blame free course where together we fix the things that are broken and produce unity instead of destruction

Parkinson's Disease Stem Cell Sequel

By Amy Price PhD

I found an interesting addition to the Parkinson's post's in the form of an article from Nature. Many thanks from helpful individuals at the Open University in the UK for passing this on.

In the article in Nature Suchowersky O. Transplantation therapy for Parkinson disease: the good, the bad and the enigmatic. Nature clinical practice. Neurology. 2008 Sep;4(9):465
Parkinson disease (PD) affects an estimated 1 million cases in North America . Motor symptoms in PD initially
respond well to dopaminergic replacement medications, but because PD progresses the drugs gradually lose effectiveness after about 10 years resulting in gait dysfunction and complications such as dyskinesias
PD is not just a disorder of the dopaminergic system but involves other neurotransmitter systems which inform autonomic dysfunction, mood disorders, fatigue, pain, sleep disorders and cognitive function. Dopaminergic cell replacement, even if successful is thought capable of treating only motor symptoms.
Over 20 years ago, transplantation of fetal ventral mesencephalic cells into the putamen was
performed on a small sample of participants with reportedly good results. Regrettably further studies with larger participant pools failed to confirm the initial reports (Freed CR et al. [2001] N Engl
J Med 344: 710–719). PET and pathological analyses revealed adequate survival of grafted
neurons, and there was untreatable runaway dyskenesia. However clinical benefit was seen in
a small subset of patients, 16 years on autopsy results are available Mendez et al. showed survival of
grafts without PD pathology for 14 years in five patients (Mendez I et al. [2008] Nat Med14: 507–509). Another patient showed good clinical improvement l 5 years plus, before gradual worsening of motor function and development of gait and balance problems (Kordower JH et al. [2008] Nat Med 14: 504–506). Autopsy results from this patient 14 years after transplantation showed great graft survival but grafted neurons had pathological
changes typical of PD, including Lewy bodies and activated microglia (cell scavengers) were seen in large numbers
Liet al. reported similar graft pathology in three patients up to 16 years after transplantation (Li JY et al. [2008] Nat Med 14: 501–503). These results indicate that for stem cell therapy to be effectual long term in D research needs to be initiated to investigate the spread to youn grafted neurons and determine strategies to resolve this issue. I would hope that advancement in the area of Adult Stem Cell research will make this possible in the near future.

I am finding the stem cell story is not so new. I did hear about a very young women stricken with metasticized spinal cancer who was treated at Sloan Kettering with grown out adult stem cells taken from her own bone marrow over fifteen years ago. She is now a successful professional with no trace of malignancy in her body. I also remember twenty five years ago in Canada I knew three terminal patients who underwent adjustments to the bone marrow transplant protocol that involved growing out their own bone marrow cells. One person enjoyed a year free from blood cancer and then relapsed but the other two lived. It is strange that when I go to Pub Med , Google Scholar or even the University library there is no trace of this research performed for "humanitarian reasons"

There is also a lot of interest in the London Project where stem cell trials are close to human trials for those with macular degeneration. Pfizer is quoted as expected to announce backing of stem cell therapy, apparently with joint labs in Cambridge Mass and Cambridge UK but on the Pfizer site I didn't see this in place.

Individuals are reporting encouraging success for adult stem cell treatment where they are thier own donors particularly for orthopedic and cardiac applications. These treatments are largely privately funded. It would be great to see this in the mainstream covered by insurance and available for people regardless of income levels

A Pill For Memory? Piracetam Revisited

By Amy Price PhD

One significant problem in traumatic brain injury is that secondary cell death occurs when the injured cells block the path for the other cells to get oxygen. One product that is used extensively in other countries but not the USA is Piracetam. It is interesting that research in pub med is showing promise for efficacy in human trials. There have been rat, rabbit, and fruit fly trials available for years but there is a lot that can differ between these and seeing actual human benefit.

I used this product to good effect many years ago without side effects and am encouraged to see studies supporting its effectiveness. The alternatives available to many people with TBI as far as psychotropic meds to restore some measure of function are concerned can sometimes have unexpected reactions or be of no effect.

Piracetam has been shown to alter the physical properties of the plasma membrane by increasing its fluidity and by protecting the cell against hypoxia. It increases red cell deformability and normalizes aggregation of hyperactive platelets according to Winnicka K, Tomasiak M, Bielawska A (2005) They are saying treatment with piracetam improves learning, memory, brain metabolism, and capacity by the interaction of this molecule with the membrane phospholipids to restore membrane fluidity . The draft below is from smart publications

The positive therapeutic effects of piracetam on cognitive (memory, attention, executive functions) and motor (coordination) functions as well as the speed of cognitive and motor performance were demonstrated in a study done by Zh Nevrol Psikhiatr Im S S Korsakova. 2008 for adolescents who sustained TBI's.

Its efficacy is documented in cognitive disorders and dementia, vertigo, cortical myoclonus, dyslexia, and sickle cell anemia according to Winblad B (2005).

The results of a meta-analysis Waegemans T, Wilsher CR, Danniau A, Ferris SH, Kurz A, Winblad B. (2002) demonstrate a difference between those individuals treated with piracetam and those given placebo, both as significant odds ratio and as a favourable number needed to treat. While there may be problems in meta-analyses and the interpretation of the statistical results, the results of this analysis provide compelling evidence for the global efficacy of piracetam in a diverse group of older subjects with cognitive impairment.

More Than a Wheel Chair

I recently enjoyed a great flight with a group called Paralysed Veterans of America. People of all shapes, sizes and conditions along with dedicated physicians and carers formed a mighty team. These men were on their way to Aspen to ski and they were fun to be with. Even with missing legs,arms, spine injury, blindness, deafness or brain injury their zest for life and care for others was an example of power and unity at work.

The conversation was full of hope for new treatments, medications, regenerative medicine and ways to improve life for their fellow man. They do research,create equipment to make life easier, and help others navigate paperwork so families can put their lives back together

As we talked I learned they do more than ski and race cars. They have lobbied congress on behalf of all of us who are disabled so we are able to use commercial transportation, be treated with courtesy and receive the assistance to get from one location to another. Getting the luggage and extra equipment a disability brings from the customs hall to the next flight, or negotiating airplane steps can appreciate the complications well timed assistance can bring.If you encounter problems travelling with a disability this site can show you what to do They mentor the newcomers on the way out of the old life before the trauma into a destiny where life is not over or lessened it is just different. I heard no useless platitudes like "Get over it, others are worse off" but rather things like "Buddy have you tried this?" or "It will get better, I will go with you".

I was empowered by the raw courage in the face of obstacles others had deemed impossible and their group willingness to give life another chance. Most of these men face daily pain, memories they can not lose and disability yet their indomitable spirits did not quit and they helped each other.

I saw courage and dignity more clearly than in a military parade or in troops ready for action...these men showed us how to live after the party is over and they did it well.

To find out more about them or to donate to make these kind of trips possible see this link I like to remember that their gift of service and the price they paid allows me to walk in freedom. Life is all about giving back to the foundation. When each of us does our part the foundation will be there for us and those who come after us
