Exercise may protect myelin

After just one day of increased stretching exercises in addition to my usual hiking my legs are feeling better. The stretching exercises for lymphedema shared in a video link in the last post help move fluid by muscle power. Lymphatic vessels run parallel somewhat to the blood vessels but have no heart pumping action to circulate the fluid to the lymph nodes where it mingles with blood vessels and immune system white blood cells. The movement of the surrounding muscles is needed to help move fluid through the lymphatic vessels. They are near the skin surface so very gentle massage motions towards the areas of drainage can also help. Lymphatic massage is a special type of massage that may be medically recommended after lymph node surgery or for lymphedema. (Read more: How to Perform Lymphatic Drainage Massage.)

Exercise can help reduce inflammation by promoting the movement of the fluid around cells and in the lymphatic vessels to lymph nodes for detoxification and eventual excretion once it is absorbed into the blood vessels. Exercise has also been found helpful for mitochondrial health which help provide the body energy and protect against myelin loss. (1)

  2. Advances in Cellular Neurobiology, Chapter: Demyelination, by F. J. Seil (1982), Unrelated to exercise: Figure 1, Bovine basic myelin protein structure includes 25 molecules of glycine within a chain of 169 amino acids and this type of protein was thought to be involved in encephalopathy. page 242, What was related to lymph nodes was on page 263, the serum of patients with demylinating disorders can cause demylination in lab animals so autoimmune type antibodies against myelin were suspected to be present. Science isn’t easy and takes a long time. My take home point: I will continue to exercise in the kitchen preparing meals with foods that were not grown with glyphosate containing herbicides such as Roundup.   https://books.google.com/books?id=R5niAgAAQBAJ&pg=PA261&lpg=PA261&dq=lymph+nodes+and+demyelination&source=bl&ots=RHxSRpXesy&sig=7HAJMmHVjCARnAFlwNfCy2F54As&hl=en&sa=X&ved=2ahUKEwjsvYW3vtTcAhVNWq0KHYIFDtw4ChDoATACegQICBAB#v=onepage&q=lymph%20nodes%20and%20demyelination&f=false

The importance of glycine within the Bovine basic myelin protein seemed visually obvious, however I itemized all of the amino acid chain just to double check. Glycine is most prevalent and the other point that became clear is that most amino acids (cysteine is not included) are incorporated so having a good variety of protein foods in the diet including all the essential amino acids would be important:

  1. Gly – glycine – 25     (Conditional, may be needed in diet)
  2. Arg – arginine – 18   (Conditional, may be needed in diet)
  3. Ser – serine – 18        (Conditional, may be needed in diet)
  4. Ala – alanine – 14      (Nonessential, we can make it)
  5. Lys – lysine – 13          (Essential in the diet)
  6. Pro – proline – 12       (Conditional, may be needed in diet)
  7. His – histidine – 10       (Essential in the diet)
  8. Leu – leucine – 10         (Essential in the diet)
  9. Asp – aspartic acid – 9   (Nonessential, we can make it)
  10. Gln – Glutamine – 8        (Conditional, may be needed in the diet)
  11. Phe – phenylalanine – 8   (Essential in the diet)
  12. Thr – threonine – 7        (Essential in the diet)
  13. Tyr – tyrosine – 4           (Conditional, may be needed in the diet)
  14. Ile – isoleucine – 3         (Essential in the diet)
  15. Val – valine – 3               (Essential in the diet)
  16. Asn – asparagine – 2      (Nonessential, we can make it)
  17. Glu – glutamic acid – 2  (Nonessential, we can make it)
  18. Met – methionine – 2      (Essential in the diet)
  19. Trp – tryptophan – 1      (Essential in the diet)
  • Ac -acetyl group – 1
  • N -nitrogen, an element – 1
  • COOH – a carboxyl group – 1

Regarding links and research

The links I collect may include research studies that don’t seem to be directly about the point I made – sometimes research hasn’t been performed yet and I’m referring to background information in the article to which I linked or I’m drawing inferences from the research that the research authors did not include. Frequently research studies are focused on finding ways to make a medication or technique that can be patented. I am trying to figure out how normal and abnormal physiology may be affected by diet or lifestyle.

Read and live at your own risk. Medical doctors practice the provision of medicine – at least so I was informed by one medical doctor. My training was regarding diet for the lifespan in health and sickness, from perinatal/prenatal, through lactation and introduction of solid foods, to childhood and teen growth spurts through adulthood and into the typical changes in metabolism that occur with aging. Chronic disease is not a typical part of aging but a slowing down of metabolism and reduced need for total calories in combination with an increased need for protein and other trace nutrients is normal. Reduced appetite and thirst signals may also be normal so remembering to eat and drink enough can be a problem during aging.

I care a lot but there are only so many reading hours in a day.

Links on Alzheimer’s, diabetes, insulin and P38 MAPK

P38 MAPK can be activated by insulin. (1Insulin is also a growth factor; it is not just a hormone involved with sugar metabolism. Blocking Cannabinoid Receptor type 1 was found to inhibit the activation of P38 MAPK by insulin or insulin-like growth factor. (2) Malfunction of insulin’s growth factor function may be involved in Alzheimer’s Disease (3) as almost 200 pharmaceuticals designed to decrease levels of amyloid or tau protein have not been found effective for treatment of the disease in humans. (See previous post.) Mouse models may not be representative of the disease process in humans.

Habits save energy, will power uses energy

In a previous post recently I briefly discussed habits and working towards change. Three weeks to build a habit is an educational message – translational research – that has been shown to be inaccurate. Newer research suggests that two months may be more realistic – an average of 66 days.

I haven’t read the original research for either recommendation however a discussion of how habits can save energy while the use of will power actually seems to deplete our energy, and can lead to less ability to stick to a plan and act impulsively, is available here: Strengthen Your Willpower by Creating New Habits, by Isaiah Hankel, Ph.D. (https://www.isaiahhankel.com/strengthen-your-willpower-by-creating-new-habits)
