For a review of some of the abstracts and information discussed at the FATEPRIDE June meeting in Iceland go to the link:

http://www.arp-manchester.org.uk/documents/FINALDetailedProgrammeandAbstracts.p

You will find such statements as:

Since World War II world soils have been "mined" for nutrients. This is because of the fact that in the developed world conventional agriculture only puts major nutrients into the soil in the form of N:P:K fertilisers. These fertilisers sometimes have added iron and calcium, in the case of acid soils, is added as lime. As a result food stuffs in the UK are up to 75% depleted in various minerals and trace metals relative to values half a century ago.

Minerals are fundamental for biochemical reactions in our bodies and hence our health. It is therefore not surprising that various diseases are increasing in animals and men when our soils and hence our food are so highly depleted in trace nutrients. It is of utmost importance that international organisations, including the European Commission, focus on soil protection in the immediate future to safeguard the health of people.

Diet supplementation with Manganese of Cu-deficient 129SV mice resulted, also in terminally ill animals. ...

Conclusions. The histopathological findings here reported, including microglia activation and vacuolation in the cortex, as well as the appearance of neurological signs such as ataxia and hindlimb paresis, the surprising behaviour of the C4 mice in response to Cu-deficiency resembling their response to scrapie infection, the intriguing protective effect of Mn supplementation, all these features strongly suggest that common pathogenetic mechanisms underlie neurodegeneration in Cu-deficiency and prion diseases.
(type of genetic mouse important factor when determining treatment)


Previously, it was suggested that an imbalance in brain trace elements, such as the loss of Cu and an excess of Mn might result in conditions that led to the formation of this misfolded form. However, we found that PrP itself influences Mn and Cu metabolism and a replacement of Cu in PrP-Cu complexes with Mn is highly likely when excess amounts of Cu and Mn are present. Cu depletion might obviously not be a prerequisite.

We showed that not a loss in the amount of Cu is required but an excess of Mn is sufficient. This implies that imbalances in environmental Mn entering the food chain might favor the formation of proteinase-resistant PrP as formerly predicted for the cause of scrapie, CJD and chronic wasting disease occuring in disease clusters in Iceland, Slovakia and Colorado where the soil in these specific regions is high in
Mn.

Conclusively, PrP itself influences manganese and copper metabolism and a replacement of copper in PrP complexes with manganese is highly likely under the condition of copper depletion or if excess amounts of copper and manganese are present. Taken together, our present study demonstrates the involvement of PrP in the regulation of intracellular metal ion homeostasis and uncovers copper and more severely, manganese ions as in vivo risk factors for the conversion into PrPSc.


In the FatPriDe project Imperial College have concentrated their efforts on assessing the spatial correlation between the prevalence of TSEs and soil geochemistry.

The work initially involved the collection of relevant data and consolidation into a GIS database. The first year of the project also involved analysis and geostatistical modelling of the data, focusing on the distribution of copper and manganese in Northern Europe. In the second year further work aimed to integrate the data sources available in Northern Europe, extend the analysis to include Mo and Se for the same area and produce the first maps of copper, manganese and molybdenum in European scale using the collected data sets. Further datasets on UK and European incidence rates of TSEs were compiled. Multivariate geostatistical techniques were used on these data and the geochemical maps to try to establish links between the TSEs and geochemical variables and therefore identify potential risk factors.

The results indicate that there is a possibility of a link between scrapie, BSE and soil geochemistry, and it may be recommended that future investigations into environmental exposure to trace metals take into account factors which determine their mobility.


The difficulties within the field study were linked to the omerta, or lack of cooperation, observed with many national veterinary bodies, except in Italy and in one experimental farm in France. The study thus focused on farms in Toscany, Emiglia Romagna, and Garonne Regions. All investigated scrapie affected fields, although characterized by a variety of geological and topographical conditions, were had soils with high clay content, high easily reducible manganese and extremely small free copper activity in soil solution.
(what would these national veterinary bodies stand to gain by NOT CO-OPERATING with these scientists?)

...one may conclude that indeed soil clay particles may induced the Cu-to-Mn exchange within the PrP 5th site and thus, in agreement with Molecular Dynamlics (see talk by Yves Chapron), may lead to the protein conformation change and thereafter to the development of scrapie disease.
 
i see nothing in your snipped up junk that support your theory that metals are the cause of TSE, plus, your url does not even work. nice try though kathy. AMPLIFICATION AND TRANSMISSION I.E. TAINTED FEED, you cannot dispute. ...TSS
 
Hey Kathy,
The Url doesnt work, is there a letter missing? I would love to read the article. Can you repost it. Thank you muchly!

Mad Cows and Metals
By Katherine Unger
ScienceNOW Daily News
31 May 2006

The proteins that, when mangled, cause "Mad Cow" and similar diseases also help regulate how yeast cells metabolize metals, biochemists report. Exposure to high levels of metals can coax proteins called prions to adopt an abnormal disease-causing conformation, the researchers found. That could explain why outbreaks of prion diseases have popped up in Iceland, Slovakia, and Colorado--regions with soils high in manganese.
Mad Cow disease in cattle, scrapie in sheep, and Creutzfeldt-Jakob disease in humans are all deadly and transmissible conditions in which the brain degenerates. All seemed to be caused by prion proteins that have changed shape so that enzymes can no longer break them down. This altered conformation is widely thought to be responsible for the diseases, because the tangled and essentially indestructible proteins collect in brain tissue (ScienceNOW, July 29 2004). Studies have shown that some metals bind to prion proteins, leading some scientists to wonder whether metals are involved in the shape shift.

Now, biochemist Gerd Multhaup of the Free University of Berlin and colleagues have shown that prions alter metal metabolism in yeast. As a first step, they took a species of yeast that does not normally make prions and added prions that don't cause disease. Copper levels increased 1.6-fold inside these cells while manganese decreased by half compared to yeast without prion proteins, the researchers report in a paper to be published 13 June in Biochemistry. The researchers then added copper or manganese to the growth medium to form 1 to 5 millimolar concentrations; both additions transformed the prions to the indestructible form.

At one time a skeptic, Multhaup says the new findings and prior evidence are starting to convince him that exposure to metal-enriched food and soils "is a risk factor" that increases susceptibility to prion diseases.

David Brown, a neurochemist at the University of Bath in the United Kingdom, doesn't go that far but says the paper is "a good confirmation" that metals strongly influence prions. And yeast molecular biologist Mick Tuite of the University of Kent in the United Kingdom says that "any attempt to try and model prion conversion in vivo is an important step forward." But he questions the relevance of a yeast species that doesn't usually have prions and says more work in necessary to prove prions behave the same way in mammals.

Introduction

The work proposed here brings together top EU geo and biochemists focusing
on determining the environmental factors that affect the development of
prion diseases such as scrapie, bovine spongiform enchpalitis (BSE), chronic
wasting disease (CWD) and Creutzfeld-Jacobs disease (CJD). First the
geographical distribution of manganese and copper in soils will be
investigated as risk factors. This will be undertaken due to the fact that
prion diseases often are found in clusters. It now has been established that
the normal metal for prion protein is copper but if that metal is replaced
with manganese, the structure of the prion protein is altered. The role of
organophosphate pesticides will also be investigated because it has been
suggested that copper is complexed with organophosphate, preventing copper
absorption.

Objectives

There is clear evidence that the occurrence of prion diseases often has a
non-random distribution, suggesting a link to some environmental factors.
The work proposed here will investigate risk factors, including the role of
trace elements and organophosphates. Analysis of regional variation in local
manganese/copper levels will be determined and compared to the incidence of
the diseases. The ability of manganese and/or organophosphates in
influencing conversion of the prion protein to an abnormal and/or infectious
protein will be determined. In combination with geographical occurrence and
geo-chemical considerations this program will identify whether these
environmental considerations should be acted upon to bring about effective
prevention or at least risk minimalisation of prion diseases in the EU and
further afield.

Description of the Work

Recently it has been suggested that disbalance in dietary trace-elements
and/or exposure to organophosphates might either cause or be a risk factor
for prion disease development. In particular, high incidence of scrapie
(e.g. in Iceland), chronic wasting disease, and in Slovakia and Italy CJD
are associated with regions where soil and foliage are reported to be low in
copper and high in manganese. This proposal will address whether exposure to
a diet that has a high manganese/copper ratio can influence prion disease
will also be addressed. In particular, we shall investigate this theory at
the level of protein, cells, animals as well as geographical and
geo-chemical associations with prion diseases. Animal models of prion
disease and sheep from farms in regions of high scrapie will be investigated
for a possible influence of level of manganese and copper on incidence or
onset of these diseases. Bio-chemical and biophysical techniques will be
used to investigate interaction of the prion protein with copper and
manganese to determine the mechanism by which Mn substitution for Cu
influences conversion to the abnormal isoform of the protein and whether
such conversion results in protein that is infectious in mouse bioassay for
infectivity. Additionally, a cell culture model will be used to generate
abnormal prion protein by exposure to manganese. Cell culture model of
infection will be used to assay whether prion disease alters manganese
metabolism and transport of manganese into cells. The level of expression of
the prion protein is in itself a risk factor for prion disease as it
shortens the incubation time for the disease. This research will result in
understanding of the role of disbalance in the trace elements Cu and Mn on
the onset and mechanisms behind the occurrence of prion diseases and will
for the first time define whether there are environmental risk factors for
prion diseases.

Milestones and Expected Results

The study proposed here will produce a geo-chemical map of Europe for
manganese and copper. These maps will be used to target field areas where
prion diseases have occurred as clusters. The bio-chemical studies will
establish whether the replacement of manganese for copper in prion protein
is a risk factor for the disease _development_. Organophosphate will also be
investigated as a risk factor. The study aims at minimising the risk of
prion diseases for humans and animals in the EU.

a) As regards the involvement of organophosphates in the origin of BSE, no
new scientific
information providing evidence or supporting the hypothesis by valid data
became
available after the adoption of the last opinion of the SSC on this issue.
Consequently
there is no reason for modifying the existing opinions.
b) Regarding the possibility of OP poisoning, the European legislation for
registration of
plant protection products and veterinary medicines ? addressed in the
enquiries ? provide
the basis for safe use of registered compounds and their formulations.
Regarding the
alleged intoxication cases reported and OP exposure it must be concluded
that safety
measures may not have been strictly followed.

transmission studies do not lie, amplification and transmission!

Oral transmission of kuru, Creutzfeldt-Jakob disease, and scrapie to
nonhuman primates.

Gibbs CJ Jr, Amyx HL, Bacote A, Masters CL, Gajdusek DC.

Kuru and Creutzfeldt-Jakob disease of humans and scrapie disease of
sheep and goats were transmitted to squirrel monkeys (Saimiri
sciureus) that were exposed to the infectious agents only by their
nonforced consumption of known infectious tissues. The asymptomatic
incubation period in the one monkey exposed to the virus of kuru was
36 months; that in the two monkeys exposed to the virus of
Creutzfeldt-Jakob disease was 23 and 27 months, respectively; and
that in the two monkeys exposed to the virus of scrapie was 25 and
32 months, respectively. Careful physical examination of the buccal
cavities of all of the monkeys failed to reveal signs or oral
lesions. One additional monkey similarly exposed to kuru has
remained asymptomatic during the 39 months that it has been under
observation.

and for Gods sake, if someone is smearing this cr@p all over there kids
heads for lice and did not come up with a TSE, i would say this is good case
study;


UK FARMER WITH BSE


1) None of our animals that contracted BSE were treated with OP's, even
in utero.
2) My kids were treated with OP's as infants to control head lice. This
seems to be endemic as infection waves in UK primary schools (and
possibly elsewhere).
3) One might argue if the continued use of british beef in the UK was
ethical, none the less it happened. We have a duty to learn from it, not
least a duty to learn on behalf of those people who died so horribly....

Abstract:
CHRONIC (2 day) exposure of human neuroblastoma cells to the organophosphate
pesticide phosmet induced a marked concentration-dependent increase in the
levels of PrP present on the cell surface as assessed by biotin labelling
and immunoprecipitation. Levels of both phospholipase C (PIPLC)-releasable
and non-releasable forms of PrP were increased on the plasma membrane. These
increases appear to be due to post-transcriptional mechanisms, since PrP
mRNA levels as assessed by Northern blotting were unaffected by phosmet
treatment. These data raise the possibility that phosmet exposure could
increase the _susceptibility to the prion agent by altering the levels of
accessible PrP_.

WHAT some of the OPiest/Metalist dont understand (refuse to understand to
further there plight to squash the truth of the ruminant feeding spreads and
amplifies the TSE agent) is that no where in science literature does it show
that Phosmet or metals _CAUSE_ TSE, there is a big difference. TO distort,
confuse, lie about the true aspect of this theory into trying to make people
believe that Phosmet and or Metals _CAUSE_ TSE, only weakens the whole
aspect of the study. but there will always be those that cannot admit the
truth about the amplification and transmission of TSE, want to blame others,
and will continue this deceit. ...TSS

Flounder,

rant all you want, the bubble will burst!

The evidence is piling up about the replacement of copper on the prion protein by other metals, like manganese, which causes the protein to malform.

Judith, and other even flounder,

What really bothered me about what I saw, was that a deficiency in copper may not be a requirement for disease. The one abstract states an excess of copper and an excess of manganese could still potentially see the manganese replace copper on the prion, especially at the internal 5th and 6th locations (not found at the octapeptide repeat area on N terminus).

The mineral supplements up here in Alberta, ALL have very high levels of manganese and about half, or less, the amount of copper. This is NOT SAFE. I will definitely have to have a individual mineral supplement blended for our cattle, as we all should if we can't find mineral supplements without the excess manganese.

This even transcends to human multivitamins. I have found only one mainstream Jamison brand multivitamin without manganese (potency level II). All the others have higher than copper levels of manganese, especially senior formulas. THIS IS NOT SAFE EITHER.

Try the link below. I seemed to miss the df on the end. You can probably find it yourself by googling "FatePride" "roles of trace metals in disease", and looking for a similar webpage like the one I had found.
