RE: Shipyard workers and references -- Second try

?? John,

 

Thought I had already sent additional refs:

 

"Hi Jack,



"Didn't mean to propose that particular paper/story was the one, just

that it's a good "take" on the discovery of such results. There are

dozens of such experiments, with totally consistent results, a few of

which are also at:

http://cnts.wpi.edu/rsh/Data_Docs/1-3/2/132list.html



"The Planel 1987 HPJ paper provides some insight on the history of their

results.



"Regards, Jim"

 

Ther are more, but not on the site. Not too many, after all, the funding

agents get to know what they don't want to see :-)

 

Does work with chemicals. "Hormesis" is intrinsic to biological

organisms (not to radiation), or life wouldn't be viable. Radiation is

just another physical stressor, like heat, that stimulates hsp80, p53,

bcl, SOD, and dozens of other genes, proteins, enzymes and other

signaling mechanisms to respond to strengthen the immune capacities,

repair mechanisms, e.g., cell cycle delay, to enhance fundamental

biological functions, resulting in better health and longevity. These

respond just the opposite at higher doses/stresses, producing toxic

effects, primarily a dose-rate (not dose) dependent response that

produces error in repairs. See, e.g.:

 

http://cnts.wpi.edu/RSH/Docs/Mitchel-Boreham/MitchelMunich01presentati_f

iles/Mitchel01MunichPres.htm 

 

http://cnts.wpi.edu/RSH/Docs/Liu/Liu-Munich/Liu_Munich_2000.htm 

 

and other papers at:

http://cnts.wpi.edu/RSH/Docs/index.html 

 

We have many papers on this that should be added in the next month or

so. But you can find a lot on MedLine.

 

Regards, Jim

	Jim,

	I was always worried about the health of paramecium.  Do you

know if they

	seek out radiation sources in the wild?

	

	I think the comments by the authors are interesting, noting my

emphases.  Do

	you know if any studies were done on adding free-radicals

chemically to the

	growing media?

	

	        "The data show clearly that under certain *ill-defined*

but

	reproducible conditions capable of autonomous existence are

stimulated to

	grow and divide by continuous exposure to *very low dose rates*

of either

	corpuscular or electromagnetic radiation of an energy."

	

	        "At the present time one can *only speculate* concerning

the modes

	of

	action and sites of origin of the stimulant. An attractive and

plausible

	hypothesis may be based on the production of free radicals by

the absorbed

	energy and the stimulation by such radicals of metabolic

activities. Low

	doses rates would produce *radicals or other reaction products*

in amounts

	small enough to be stimulating while high dose rates would lead

to toxic

	concentrations of the same or other substance."

	

	I think the RSH should seek more paramecium research efforts.
