hi bill:

usually you are level headed

i understand your pessimism

but

in the past 3 years since diagnosis of PD

i have been paying attention to these sorts of announcements

some of the work that Levesque does has been published

see below

also, growing stem cells in vitro is a new field of tissue culture

growth factors, timing, new gene discoveries about development

will only accelerate as results come from stem cell studies now being

aproved by NIH

Jim Finn is walking ad for fetal porcine implants for PD

also, not all the fetal transplants were negative in the Freed study of

human fetal transplants

(that paper is available free on the web)

he says stem cells next, but, some way has to be devised

to reduce the implant cell population if symptoms get too extreme

like with controlled exposure to a rare antibiotic that they are made

the subject of the experiment had the brain cells removed during a DBS

procedure

still dangerous

here in Minnesota, one of the doctors (Abbott Northwestern Hospital)

initially was doing brain biopsies and cites the number of successful

biopies

as his experience for performing DBS

which is probably easier from a routine/repeatable standpoint

targeting one area -- than the many of biopsies

dopamine activity can be assessed with

PET and SPECT scans using radioactive dopamine

that is how my neurogist would like to better define my " probable " MSA

and distinguish it from PD

but, we have to see if insurance will cover the expense

my Mom (85) died last year

and she had a PET scan for her lung cancer

radioactive glucose was used and is metabolized faster by tumors than

normal tissue

and it was covered by Medicare and her private insurance

all $5,000

heck I just had my second MRI

at $2,000 each

and it is not conclusive

there has been recent discussion about " neuro protective " properties of

dopamine agonists

as defined in studies of progresson useing these scanners on people

with Parkinsons

Presurgical contribution of quantitative stereotactic positron emission

tomography in temporo limbic epilepsy.

Epilepsy and Brain Mapping Program, Cedars-Sinai Medical Office Towers, Los

Angeles, California, USA.

BACKGROUND: We quantified the interictal metabolic changes associated with

temporal lobe epilepsy by using an accurate stereotactic method. METHODS: We

selected 16 patients who had proven unilateral focal or regional temporal onset

defined by SEEG criteria. Each patient underwent stereotactic MRI and

stereotactic [18 fluoro] fluorodeoxyglucose positron emission tomography (PET).

RESULTS: Asymmetries (mean, +/- SD) were found in mesio-temporal structures:

amygdala (-0.033+/-0.027, p = 0.0002), hippocampus (-0.035+/-0.032, p = 0.0006),

and superior temporal gyrus (-0.036+/-0.032, p = 0.0004). Four of the sixteen

patients had previously had unlocalized qualitative nonstereotactic PET

analysis. CONCLUSIONS: The quantitative stereotactical PET method allows a

higher resolution study of mesio-temporal structures.

Fetal and adult human CNS stem cells have similar molecular characteristics and

developmental potential.

The mammalian central nervous system (CNS) contains multipotent stem cells that

develop into neurons, astrocytes and oligodendrocytes. Our current data show

that fetal and adult human CNS stem cell isolates display similar proliferation

kinetics, differentiate into three major cell types of the nervous system and

express similar sets of regulatory genes. However, each individual CNS stem cell

isolate could be distinguished by its specific gene expression and development

al

potential.
