Treating psychopathological symptoms will somehow resolve causes?

This 2020 Swiss review subject was potential glutathione therapies for stress:

“We examine the available data supporting a role for GSH levels and antioxidant function in the brain in relation to anxiety and stress-related psychopathologies. Several promising compounds could raise GSH levels in the brain by either increasing the availability of its precursors or the expression of GSH-regulating enzymes through activation of Nrf2.

GSH is the main cellular antioxidant found in all mammalian tissues. In the brain, GSH homeostasis has an additional level of complexity in that the expression of GSH and GSH-related enzymes are not evenly distributed across all cell types, requiring the coordination between neurons and astrocytes to neutralize oxidative insults.

Increased energy demand in situations of chronic stress leads to mitochondrial ROS overproduction, oxidative damage and exhaustion of GSH pools in the brain.

Several compounds can function as precursors of GSH by acting as cysteine (Cys) donors such as taurine or glutamate (Glu) donors such as glutamine (Gln). Other compounds stimulate the synthesis and recycling of GSH through the activation of the Nrf2 pathway including sulforaphane and melatonin. Compounds such as acetyl-L-carnitine can increase GSH levels.” “Therapeutic potential of glutathione-enhancers in stress-related psychopathologies” (not freely available)

Many animal studies of “stress-related psychopathologies” were cited without noting applicability to humans. The reviewers instead had curious none-of-this-means-anything disclaimers like:

“Comparisons between studies investigating brain disorders of such different nature such as psychiatric disorders or neurodegenerative diseases, or even between brain or non-brain related disorders should be made with caution.”

Regardless, this paper had informative sections for my 27th week of eating broccoli sprouts every day.

1. I forgot to mention in Broccoli sprout synergies that I’ve taken 500 mg of trimethyl glycine (aka betaine) twice a day for over 15 years. Section 3.1.2 highlighted the amino acid glycine:

“Endogenous synthesis is insufficient to meet metabolic demands for most mammals (including humans) and additional glycine must be obtained from the diet. While most research has focused on increasing cysteine levels in the brain in order to drive GSH synthesis, glycine supplementation alone or in combination with cysteine-enhancing compounds are gaining attention for their ability to enhance GSH.”

2. The amino acid taurine dropped off my supplement regimen last year after taking 500 mg twice a day for years. It’s back on now after reading Section 3.1.3:

“Most studies that reported enhanced GSH in the brain following taurine treatment were performed under a chronic regimen and used in age-related disease models. Such positive effects of taurine on GSH levels may be explained by the fact that cysteine is the essential precursor to both metabolites, whereby taurine supplementation may drive the metabolism of cysteine towards GSH synthesis.

3. A study in Upgrade your brain’s switchboard with broccoli sprouts was cited for its potential:

“Thalamic GSH values significantly correlated with blood GSH levels, suggesting that peripheral GSH levels may be a marker of brain GSH content. Studies point to the capacity of sulforaphane to function both as a prophylactic against stress-induced behavioral changes and as a positive modulator in healthy animals.”

Increasing carbon dioxide levels increases beneficial broccoli sprout compounds

This 2020 study used IPCC unscientific, politically-motivated, wild-ass guesses for year 2100 CO2 levels to find that broccoli sprouts – like most plants – benefit when CO2 is increased:

“Elevated CO2 (eCO2, 620 ppm, the expected IPCC-SRES B2-scenario prediction of eCO2 of the year 2100) was applied for 9 days to further improve nutritive and health-promoting values of three cultivars of broccoli sprouts.

  • eCO2 improved sprouts growth and induced GLs [glucosinolates] accumulation.
  • There were increases in myrosinase activity, which stimulated GLs hydrolysis to yield health-promoting sulforaphane.
  • Low levels of sulforaphane nitrile were detected and positively correlated with reduced epithiospecifier protein after eCO2 treatment.
  • High glucoraphanin and sulforaphane levels in eCO2 treated sprouts improved the anticarcinogenic and anti-inflammatory properties of their extracts.

In conclusion, eCO2 treatment enriches broccoli sprouts with health-promoting metabolites and bioactivities.” “Elevated CO2 improves glucosinolate metabolism and stimulates anticancer and anti-inflammatory properties of broccoli sprouts” (not freely available)

This study was sponsored in Saudi Arabia. Would gathering such scientific evidence even be permitted in more “enlightened” countries?

Performing research on obvious lies and thinking for yourself isn’t allowed anymore in most “learning” institutions. You already knew that, didn’t you?

At the end of How much sulforaphane is suitable for healthy people? I applauded my high-school literature teachers for forcing their students to demonstrate that they could think for themselves. I didn’t mention that each monthly assignment to read two books, then compare-and-contrast them in a 3-page handwritten paper, was individualized so that students couldn’t undo the assignment’s purpose with parasitical collaboration.

This former practice remains a good measure of intentional dumbing-down of young people, the purpose of which has become clearer.

Jet fuel exposure causes diseases in the great-grand offspring

This 2020 Washington State University rodent study examined how great-grandmothers’ JP-8 exposures produced diseases in their great-grand offspring:

“Ancestral exposure to environmental influences such as toxicants, abnormal nutrition, and traumatic stress can affect the germline epigenome and promote the epigenetic transgenerational inheritance of adult onset disease in various organisms from plants to humans. Biological mechanisms underlying transgenerational epigenetic inheritance induced by jet fuel exposure are further investigated in the current study.

Genome-wide association studies (GWAS) have found specific genetic mutations associated with human pathologies, however these genetic mutations generally appear in less than 1% of the disease population. In contrast, epimutations (DNA methylation, histone modifications, non-coding RNA, chromatin structure, and RNA methylation alterations) seem to have a higher frequency and appear in more individuals with the diseases. Determining epigenetic biomarkers for these diseases could become especially useful indicators of environmental exposures and disease susceptibility in the human population.

The number of differential methylated regions (DMRs) found in the transgenerational F3 males is between 100 and 500 for each individual pathology. Few DMRs overlap between the different pathologies which supports the possible use of epimutations as biomarkers of disease. Although further studies are required, the lack of a subpopulation of DMRs overlapping with all pathologies suggests that at a more stringent statistical threshold there are not common DMRs among specific diseases.

Although females develop transgenerational disease, insufficient numbers of oocytes can be obtained on individuals to allow epigenetic associations to be assessed. The study only examined male pathology and associated sperm epimutation associations.” “Epigenome-wide association study for transgenerational disease sperm epimutation biomarkers following ancestral exposure to jet fuel hydrocarbons”

The only associations these study subjects had with JP-8 were their great-grandmothers’ jet fuel exposures while pregnant with their grandparents. Other environmental toxicants studied by this group that produced similar transgenerationally inherited diseases were DDT, atrazine, and vinclozolin.

Ever think about your great-grandchildren?

Unraveling oxytocin – is it nature’s medicine?

This 2020 review attempted to consolidate thousands of research papers on oxytocin:

“Chemical properties of oxytocin make this molecule difficult to work with and to measure. Effects of oxytocin are context-dependent, sexually dimorphic, and altered by experience. Its relationship to a related hormone, vasopressin, have created challenges for its use as a therapeutic drug.

Widely used medical interventions i.e.:

  • Exogenous oxytocin, such as Pitocin given to facilitate labor;
  • Opioid medications that block the oxytocin system; or
  • Cesarean sections that alter exposure to endogenous oxytocin

have lasting consequences for the offspring and/or mother.

Such exposures hold the potential to have epigenetic effects on the oxytocin systems, including changes in DNA methylation. These changes in turn would have lasting effects on the expression of receptors for oxytocin, leaving individuals differentially able to respond to oxytocin and also possibly to the effects of vasopressin.

Regions with especially high levels of OXTR [oxytocin receptor gene] are:

  • Various parts of the amygdala;
  • Bed nucleus of the stria terminalis;
  • Nucleus accumbens;
  • Brainstem source nuclei for the autonomic nervous system;
  • Systems that regulate the HPA axis; as well as
  • Brainstem tissues involved in pain and social attention.

Oxytocin protects neural cells against hypoxic-ischemic conditions by:

  • Preserving mitochondrial function;
  • Reducing oxidative stress; and
  • Decreasing a chromatin protein that is released during inflammation

which can activate microglia through the receptor for advanced glycation end products (RAGE). RAGE acts as an oxytocin-binding protein facilitating the transport of oxytocin across the blood-brain barrier and through other tissues.

Directionality of this transport is 5–10 times higher from the blood to the brain, in comparison with brain to blood transport. Individual differences in RAGE could help to predict cellular access to oxytocin and might also facilitate access to oxytocin under conditions of stress or illness.

Oxytocin and vasopressin and their receptors are genetically variable, epigenetically regulated, and sensitive to stressors and diet across the lifespan. As one example, salt releases vasopressin and also oxytocin.

Nicotine is a potent regulator of vasopressin. Smoking, including prenatal exposure of a fetus, holds the potential to adjust this system with effects that likely differ between males and females and that may be transgenerational.

Relative concentrations of endogenous oxytocin and vasopressin in plasma were associated with:

These studies support the usefulness of measurements of both oxytocin and vasopressin but leave many empirical questions unresolved.

The vast majority of oxytocin in biosamples evades detection using conventional approaches to measurement.” “Is Oxytocin Nature’s Medicine?”

I appreciated efforts to extract worthwhile oxytocin research from countless poorly performed studies, research that wasted resources, and research that actually detracted from science.

I was disappointed that at least one of the reviewers didn’t take this review as an opportunity to confess their previous wastes like three flimsy studies discussed in Using oxytocin receptor gene methylation to pursue an agenda.

Frank interpretations of one’s own study findings to acknowledge limitations is one way researchers can address items upfront that will be questioned anyway. Such analyses also indicate a goal to advance science.

Although these reviewers didn’t provide concrete answers to many questions, they highlighted promising research areas, such as:

  • Improved approaches to oxytocin measurements;
  • Prenatal epigenetic experience associations with oxytocin and OXTR; and
  • Possible transgenerational transmission of these prenatal epigenetic experiences.

No honorable intentions

Catching up with Martin Armstrong:

“What’s going on here? It seems to be more that government is realizing that they’re in trouble.

Everybody has deficits year after year after year. The social programs are failing. They have no intention of ever paying anything back!

This idea that they’ve going to change the economy…this is an academic utopia. This is never going to work. This is not the way things work.

When you lose your job, your future, your future is very much in flux. The Great Reset is just not going to happen.

Our model is not talking about what people talk about on Facebook, Twitter, whatever. Our models focus on what creates that to begin with. The U.S. Army, etc., are focusing on that [FB etc.] to predict what people are going to start throwing bricks at. Our model focuses on the origin, not the end game.”

“Lifting the restrictions means they have a very serious problem.

The majority are just sheep. They wear their masks and surrender all rights today and those of their children into the future. They are incapable of waking up and think the government really cares. They will be the ones with a devastating blow that will come all at once.”

Take responsibility for your one precious life – DHEA

This 2020 meta-analysis subject was DHEA:

“Twenty-four qualified trials were included in this meta-analysis. Statistically significant increases in serum IGF-1 levels were found only in participants who were:

  1. Women; or
  2. Supplementing 50 mg/d; or
  3. Undergoing intervention for > 12 weeks; or
  4. Without an underlying comorbidity; or
  5. Over the age of 60 years.

DHEA supplementation led to an overall increase of ~16 ng/ml in serum IGF-1 levels, as well as increases of ~23 [women] and ~20 ng/ml [age > 60]. Diseased and healthy subjects ages ranged from 20 to 72 years old.”

Discussion section explanations of the above:

  1. “Women are more susceptible to biochemical and clinical shifts caused by DHEA supplementation.
  2. The majority of investigations tested DHEA at a dose of 50 mg/d.
  3. The majority of studies were performed for > 12 weeks.
  4. Participants with no comorbidities were also older in many studies.
  5. Older patients have a natural decline in the production of IGF-1 and DHEA.

Additional rigorous RCTs are warranted to better define whether and to what extent changes in IGF-1 levels caused by DHEA supplementation are relevant for health benefits.” of dehydroepianrosterone (DHEA) supplementation on serum levels of insulin-like growth factor 1 (IGF-1): A dose-response meta-analysis of randomized controlled trials” (not freely available)

More on IGF-1 from The influence of zinc supplementation on IGF-1 levels in humans: A systematic review and meta-analysis which was cited for “Previous studies have demonstrated that IGF-1 levels can be affected by several factors.”

“IGF-1 is a growth factor synthesized in the liver, and elicits a myriad of effects on health due to its participation in the GH-IGF-1 axis, where it:

  • Is involved in tissue homeostasis;
  • Has anti-apoptotic, mitogenic, anti-inflammatory, antioxidant and metabolic actions;
  • Contributes to skeletal muscle plasticity, maintenance of muscle strength and muscle mass;
  • Neural and cardiovascular protection;
  • Development of the skeleton;
  • Possesses insulin-like effects, and
  • Is a key factor in brain, eye and lung development during fetal development.

IGF-1 plays important roles in both growth and development, and its levels vary depending on age, with peaks generally observed in the postnatal period and at puberty. IGF-1 levels influence the release of GH [growth hormone] from the hypophysis [pituitary gland] via a negative feedback loop.

A rapid decrease in IGF-1 levels is registered during the third decade of life. Levels gradually decrease between the third and the eighth decade of life.”

The Group 3 “> 12 weeks” finding was reinforced by perspectives such as:

Group 4 “with no comorbidities” was narrowly defined. All of us have degrees of diseases in progress. Consider aging effects:

  • Aging as a normal disease “Aging and its diseases are inseparable, as these diseases are manifestations of aging. Instead of healthy aging, we could use the terms pre-disease aging or decelerated aging.”
  • Aging as an unintended consequence “Epigenetic ageing begins from very early moments after the embryonic stem cell stage and continues uninterrupted through the entire lifespan. Ageing is an unintended consequence of processes that are necessary for development of the organism and tissue homeostasis thereafter.”
  • Organismal aging and cellular senescence “If we assume that aging already starts before birth, it can be considered simply a developmental stage, required to complete the evolutionary program associated with species-intrinsic biological functions such as reproduction, survival, and selection.”
  • An environmental signaling paradigm of aging “The age-phenotype of a cell or organ depends on its environment and not its history. Organisms, organs, and their cells can be reset to different age-phenotypes depending on their environment.”

These perspectives are less important than what each of us choose to do about our own problems. Take responsibility for your one precious life.

Get serious about advanced glycation end products (AGEs)

Ever heard about AGEs? Here are three papers that describe how AGEs affect humans.

First is a 2020 Italian review Common Protective Strategies in Neurodegenerative Disease: Focusing on Risk Factors to Target the Cellular Redox System:

“Neurodegenerative disease is an umbrella term for different conditions which primarily affect the neurons in the human brain. Currently, neurodegenerative diseases are incurable, and the treatments available only control the symptoms or delay the progression of the disease.

Neurotoxicity can be induced by glycation reactions. Since glycation is a nonenzymatic process, proteins characterized by a slow turnover are those that more easily accumulate AGEs.

Methylglyoxal (MG) can occur as glycolysis by-product, but it is also present in foods (especially cooked and baked), beverages (mainly those fermented), and cigarette smoke, and it is considered the most potent precursor of AGE formation. More than 20 different AGEs have been identified in foods and in human tissues.

AGE accumulation, oxidative stress, and inflammation are related to AGE ability to bind specific receptors called RAGE. RAGE expression increases during aging, cancer, cardiovascular diseases, AD [Alzheimer’s], PD [Parkinson’s], and other neurodegenerative diseases.”

A 2015 study by some of the same authors Antiglycative activity of sulforaphane: a new avenue to counteract neurodegeneration? was cited for a treatment in addition to changing one’s diet to be AGE-less.

“When MG production is increased by high glucose or oxidative stress, glycated proteins accumulate in the brain and lead to glycative stress, playing a fundamental role in the establishment of different neurodegenerative disorders.

Our results indicated that SF [sulforaphane] counteracts ROS by two possible mechanisms of action: an increase of intracellular GSH [glutathione] levels and an enhancement of MG-detoxification through the up-regulation of the glyoxalase (GLO1) systems. GLO1 up-regulation is mediated by the transcription factor Nrf2. SF has been demonstrated to activate Nrf2.

Another mechanism by which SF exerts its neuroprotective activity against MG-induced glycative damage is the modulation of mitogen-activated protein kinase (MAPK) signaling pathways involved in apoptotic cell death. All MAPK signaling pathways are activated in AD.

Brain-derived neurotrophic factor (BDNF) is associated with neuronal survival through its interactions with the tyrosine receptor kinase B (TrkB) and p75 cellular receptors. BDNF expression levels are reduced in the brain of AD patients. SF pre-treatment, before MG addition, not only further increased BDNF levels, but also significantly induced TrkB protein levels reverting MG negative effect on this receptor.

SF totally reverts the reduction of glucose uptake caused by MG exposure. SF can be defined as a multitarget agent modulating different cellular functions leading to a pro-survival frame of particular importance in the prevention / counteraction of multifactorial neurodegenerative diseases.”

A 2020 review Non-enzymatic covalent modifications: a new link between metabolism and epigenetics investigated glycation:

“Non-enzymatic covalent modifications (NECMs) by chemically reactive metabolites have been reported to manipulate chromatin architecture and gene transcription. Unlike canonical post-translational modifications (PTMs), NECMs accumulate over time and are much more dependent on the cellular microenvironment.

A. Guanine residues in DNA and RNA can undergo methylglyoxal glycation, thereby inducing DNA and RNA damage. This DNA damage has few corresponding repair pathways.

B. Histones are primary glycation substrates because of their long half-lives and abundant lysine and arginine residues. Histone glycation was found to induce epigenetic dysregulation through three distinct mechanisms:

  1. Competition with essential enzymatic PTMs for sites (e.g., glycation adducts replace H3K4me3 and H3R8me2);
  2. Changing the charge states of histone tails and subsequently affecting the compaction state of the fiber; and
  3. Altering three-dimensional chromatin architecture by inducing both histone-histone and histone-DNA crosslinking.

Epigenetic impacts of histone glycation were shown to be dependent on sugar concentration and exposure time. Histone and DNA glycation may lead to long term epigenetic impacts on immune responses.

C. Glycation of multiple lysine residues of NRF2 inhibits its oncogenic function. Sugar molecules can influence epigenetic events through glycation of transcription factors and/or their associated regulatory proteins.”

The Transcription factor glycation section referenced a 2011 paper Regulation of the Keap1/Nrf2 system by chemopreventive sulforaphane: implications of posttranslational modifications:

“Nrf2 mRNA level is unaffected by treatment with sulforaphane, suggesting that cellular expression of Nrf2 protein is posttranscriptionally regulated. Posttranslational modifications of Keap1 and Nrf2 proteins seem to play an important role in the regulation of ARE‐dependent gene expression.”

Part 3 of Do broccoli sprouts treat migraines?

This 2019 Swedish review subject was the role of inflammation in migraines:

“In this article, we argue that inflammation could have an important role in migraine chronification through a mechanism termed neurogenic neuroinflammation, a phenomenon whereby activation of trigeminal sensory pathways leads to an orchestrated inflammatory response involving immune cells, vascular cells and neurons.

No studies to date have directly linked hypothalamic neuroinflammation with migraine, and we therefore looked to other studies. Overactivity of the NF-κB–IKKβ signalling pathway has been shown to be a critical modulator of hypothalamic inflammation.

We do not believe that CNS inflammation is involved in the triggering of migraine attacks, as BBB alterations, glial cell activation and leukocyte infiltration have not been observed in individuals with this condition. Peripheral sensitization is an important factor in migraine chronification, as opposed to migraine triggering.” “Does inflammation have a role in migraine?” (not freely available)

See Reevaluate findings in another paradigm for other views of hypothalamic inflammation.

I came across this review through its citation in the 2020 medical paper The fifth cranial nerve in headaches with the same lead author:

“Reduced serotonergic transmission seems to be involved in medication overuse headache development, possibly through a facilitation of the sensitization process via a maladaptive plasticity. In humans, common neurophysiological investigation of central sensitization shows an abnormal cortical response to repetitive sensory stimuli, with an increased response amplitude after low numbers of stimuli and a lacking habituation, suggesting an altered plasticity.

Neurons, under repetitive, persistent nociceptive stimuli, become sensitized and produce exaggerated and prolonged responses to lower threshold stimuli. Over time, a neuroplastic adaptation in medullary and cortical pain areas causes a shift in the pain modulatory system creating a new threshold and favouring a net pain facilitation rather than pain alleviation.

Targets are almost exclusively found in the nerves of trigeminal ganglion; the hub of the fifth cranial nerve. Although we believe that the headache-trigger most likely have the origin in the CNS, this review underscores the importance of trigeminal neurons in the perception of pain.”

This second paper listed various treatments of symptoms. It was remarkable for no focus on treatments of causes.

Per Parts 1 and 2, I rarely get headaches anymore, much less migraines. 23 weeks of eating a clinically relevant amount of broccoli sprouts every day resolved causes for me. I didn’t appreciate how migraines and many other things changed until awakening during Week 9.
