Of DNA, fossil fuel and memory

I started out, wondering if crude oil contained DNA. I was thinking of how many things we use that have an oil base and how much DNA that could mean. Of course, I thought a little about “Jurassic Park” and Dinosaur DNA and so, I GOOGLED.

I got involved with thermophilic bacterium strain C2, which has the ability to transform crude oils…and how DNA extraction from crude oil was performed by the method using zirconia beads and a stool kit. and still, I didn’t really have an answer. Obviously, there is DNA in the oil… but it would appear to be bacteria DNA.

So, I read this big long scientific study about oil and how it really isn’t dead dinosaurs. I read about how Neanderthal DNA is being extracted from fossilized bones. So far, only 1 million of the 3 billion DNA letters of the genome have been sequenced and the authors of one report are saying that it proves the complete sequence is attainable.

Then I went on a cruise of cellular memory. It seems that the molecular and cellular basis of long-term T cell memory against viral antigens remains undefined. Studies also indicate that following transfer, in the absence of antigen, memory B-cell populations are lost from the adoptive host after 10–12 weeks.

Alloreactive memory T cells participate in transplant rejection is driving new lines of research focusing on understanding the immunobiology of alloreactive memory T cells and on designing novel therapies to specifically target memory T cells.

When I got to :

"Immune responses to EBV in immunosuppressed (IS) solid organ transplant (SOTx) recipients have not been well characterized. Here we evaluate the phenotype and function of EBV-specific CD8+ T cells in peripheral blood isolated from "stable" IS SOTx recipients. The EBV-specific CD8+ T cell memory subset distribution in the peripheral blood of patients was examined by flow cytometric analysis using HLA-A2 tetramers incorporating BMLF1 (lytic), and LMP2 and EBNA3A (latent)-derived peptides, in conjunction with mAbs against the CD45RO, CD45RA, and CD62L markers. The ability of CD8+ T cells to produce IFN-gamma in response to the same EBV-derived peptides was measured by ELISPOT assay. Patients and healthy normal donors exhibited similar anti-EBV CD8+ T cell frequencies and specificities against the EBV epitopes evaluated. When compared to healthy normal donors, an overall significant expansion of the CD8+ T cell "effector memory" (CD45RO+/CD62L-) pool, including that of EBV "latent" (LMP2 and EBNA3A)-specific CD8+ T cells was detected in IS SOTx patients. However, the patients' EBV-specific CD8+ T cells showed decreased IFN-gamma production to the EBV-peptide stimulation."

I had to quit! What in the heck was I reading this stuff for?

It was interesting to read the stories of various people who had been the recipient of donor organs and who claimed, postoperative acquisition of some characteristics of the donor person.

Medical opinion is skeptical and varied when it comes to saying that organ recipients might gain more than just a lifeline from their transplants... but there was some wild stuff about a professor of medicine, neurology, psychiatry and surgery from the University of Arizona, who says his research team has found definite links of what they call 'cellular memory' and he has documented some 70 cases where he believes transplant recipients have inherited the traits of their donors.

Prof Schwartz said: "When the organ is placed in the recipient, the information and energy stored in the organ is passed on to the recipient. The theory applies to any organ that has cells that are interconnected. They could be kidneys, liver and even muscles.

"The stories we have uncovered are very compelling and are completely consistent."

His studies have found that heart transplant patients are the most likely to experience personality changes.

So, I started thinking about the shelf life of a cell. How long does each type of cell live?

I found the following statistics:

Skin cells: from 1 to 34 days
Stomach lining cells: 2 days
Red blood cells: 120 days
Liver cells: 500 days
Bone cells: 25 to 30 years
Brain cells: may live as long as you live.

Was it possible that feelings of "deja vu" were something attached to genetics? Was it possible that all of this stuff about "past lives" and reincarnation was attributable to inherited genes? I read one study that concluded that fetuses had a short-term memory of at least ten minutes and a long-term memory of at least twenty-four hours.

Then, there was the study of colour genetics in Icelandic Sheep!

There are all kinds of Family Tree DNA studies and forums. They focus on either the Patrilineal, shown by the Y chromosome which is passed whole and intact (except for rare mutations) from father to son, down through thousands of generations, from Noah to us or the Matrilineal, shown by the mitochondrial DNA which is passed whole and intact (except for rare mutations) from mother to children, down through even more thousands of generations, from Eve to us.

I think the creepiest thing that I came across was a comparison of genomes and what percentage of genes we share with other organisms.

Human to yeast about 30%
Human to worm about 40%
Human to banana about 50%
Human to fruit fly about 60%
Human to mouse about 90%
Human to chimp about 98.4%
Human to human about 99.9% (except for twins, whose genes are 100% identical)

I stopped completely after I read a report dated last April, in which paleontologists working in northern Canada announced that they had found a skeleton that may be the bridge between fish and four-legged land animals. The 375-million-year-old creature had a head like a crocodile, a body built for swimming and front legs that were some sort of cross between fins and feet.

It sounded a little too much like a guy I knew, in high school.

I haven't exhibited any of my donor's personality traits and I think making the case that liver cells might actually contain "memories" - that is a memory of a place or a person is a far stretch. Cellular memory of the type cited in your article is a completely different puppy from remembering someone's address or a face or your childhood sweetheart. It's actually a chemical/biological response that controls disease response.

However, my spiritual practice tells me that communication with those no longer living is possible (I am a Spiritualist) but I believe you have as much chance of having communication with my donor as I do if you're open to it.

I'm not sure how much stock I would put in this doctor's "study" without seeing how many people were in it and what their spiritual beliefs were beforehand.

The creepy thing to me is that there are "doctors" out there who actually want to use transplant recipients as guinea pigs in such bizarre and pointless studies at times when they are trying desperately to get back to a normal life.

Hi Buck,

I realize that there is quite a difference in the types of memory and I totally understand your spiritual practices.

I agree about the "study"- it was only one study. I do find our "Empirical" methods of science to be a little amusing. Unfortunately that does require experimenting and recording the data of experiences and I should hope that this study was made with willing, consenting subjects and not people used as "guinea pigs".

I can only imagine what it must be like to be the recipient of a transplant. I would think there is not only a physical component but a huge emotional component to recovery.

And I use the term recovery with some reluctance. As a survivor of MTBI (mild traumatic brain injury), I know that there is no such thing as mild trauma... and I know that recovery is a life long pursuit... and that sometimes our "normal life" is a new measure of normalcy.

In 1997, a multidisciplinary team published the first comprehensive guidelines for treating adult brain injury.

I can only imagine that dealing with the acquisition of a donated organ must have similar, perhaps even more daunting and complicated hurdles. I think we are at something like 53 years of practice in such procedures. Early days!

Really, the first organization of medical professionals in North Amercian was chartered in 1766, in New Jersey. We've come a long way, baby!

I am huge believer in things yet undiscovered, mysteries not even contemplated. I write, on occasion, with a sense of irony that reflects this feeling that there is so much more than we can conceive.

Perhaps that is part of my life-long interest in Spiritualism, as well.

I wish you well, Buck. Thank you for your post. I am guessing that you discovered my blog because you were surfing for information on transplants. I found the internet most helpful when I was trying desparately to get back to a normal life. Stay optimistic and hold on to the good things.

By and large, I think the world does care and most of us want to help each other.

When my father passed away (at 50 years old) in 1984, we were too busy reeling over the suddeness and didn't give a thought about organ donation. He had signed his driver's license but he died at home and they didn't take his wallet to the morgue. Fortunately, some courageous soul from the Coroner's Office called and asked if he wanted to donate- and thankfully, it was soon enough that some organs and tissue were still useful.

Some time later, we received thank you cards from various organizations- among them, a note saying that two people had been given the gift of sight. Pretty profound. Ironically, we also had a thank you for brain tissue. Perhaps my father's own cells were part of the testing that brought science closer to an understanding of brain injuries.

Best regards,

Jody
