This 2020 study followed up The transgenerational impact of Roundup exposure using the Washington State Unversity research group’s most recent methodology in DEET and permethrin cause transgenerational diseases: “The herbicide glyphosate has been shown to promote epigenetic transgenerational inheritance of pathology and disease in subsequent great-grand offspring (F3 generation). The current study was designed to … Continue reading Part 2 of The transgenerational impact of Roundup exposure
This 2019 Washington rodent study from Dr. Michael Skinner’s lab found adverse effects in the grand-offspring and great-grand-offspring following their ancestor’s exposure during pregnancy to the world’s most commonly used herbicide: “Using a transient exposure of gestating F0 generation female rats found negligible impacts of glyphosate on the directly exposed F0 generation, or F1 generation … Continue reading The transgenerational impact of Roundup exposure
This 2018 French/Italian/Swiss rodent study was an extension of the work done by the group of researchers who performed Prenatal stress produces offspring who as adults have cognitive, emotional, and memory deficiencies and Treating prenatal stress-related disorders with an oxytocin receptor agonist: “Reduction of maternal behavior [nursing behavior, grooming, licking, carrying pups] was predictive of … Continue reading The lifelong impact of maternal postpartum behavior
This 2018 Canadian paper reviewed evidence for potential sex-specific differences in the lasting impacts of childhood trauma: “This paper will provide a contextualized summary of neuroendocrine, neuroimaging, and behavioral epigenetic studies on biological sex differences contributing to internalizing psychopathology, specifically posttraumatic stress disorder and depression, among adults with a history of childhood abuse. Given the … Continue reading Sex-specific impacts of childhood trauma
Was the recent Swiss avalanche’s cause the last, triggering snowflake, or the billions of snowflakes before it? There’s been a slight increase in the number of PNAS studies that included the “catastrophic” search word from October 2016 to mid-January 2018 compared to the January 2014 to mid-April 2015 period referenced in How well can catastrophes … Continue reading The impact of the last snowflake
Continuing with Dr. Arthur Janov’s May 2016 book Beyond Belief: “p. 17 When someone insults us, we immediately create reasons and rationales for it. We cover the pain. Now imagine a whole early childhood of insults and assaults and how that leaves a legacy that must be dealt with. The mind of ideas and philosophies … Continue reading Beyond Belief: The impact of merciless beatings on beliefs
This 2015 worldwide human study Hunger promotes acquisition of nonfood objects found that people’s current degree of hungriness affected their propensity to acquire nonfood items. The researchers admitted that they didn’t demonstrate cause and effect with the five experiments they performed, although the findings had merit. News articles poked good-natured fun at the findings with … Continue reading Do the impacts of early experiences of hunger affect our behavior, thoughts, and feelings today?
What I found curious in this 2012 UK review of 82 studies was the reviewer’s reluctance to highly regard a human’s life before birth, during infancy, and in early childhood. There was no lack in 2012 of animal studies to draw from to inferentially hypothesize how a human fetal environment causes the fetus to adapt … Continue reading Problematic research: Feigning naivety of the impact of prenatal, infancy and early childhood experiences
This 2021 human study performed blood metabolite analyses: “Dementia is a collective term to describe various symptoms of cognitive impairment in a condition in which intelligence is irreversibly diminished due to acquired organic disorders of the brain, characterized by deterioration of memory, thinking, behavior, and the ability to perform daily activities. In this study, we … Continue reading Dementia blood factors
This 2021 human clinical trial investigated associations between gut microbiota and host adaptive immune system components: “Diet modulates gut microbiome, and gut microbes impact the immune system. We used two gut microbiota-targeted dietary interventions – plant-based fiber or fermented foods – to determine how each influences microbiome and immune system in healthy adults. Using a … Continue reading Changing your immune system / gut microbiota interactions with diet
Three papers on interactions of the virus and inflammatory bowel disease, beginning with a 2021 review: “Analysis signaling pathways of innate and adaptive immunity components during SARS-CoV-2 infection in IBD (inflammatory bowel disease) patients through a putative alternative route – the gastrointestinal tract, with virus attachment to ACE2 (angiotensin-converting enzyme 2) expressed on IECs (intestinal … Continue reading An IBD trigger?
This 2015 rodent study investigated interactions of Vitamins A, D, E, and K: “Significant competitive interactions for uptake were elucidated among vitamin D, E and K, supporting the hypothesis of common absorption pathways: Vitamin A – Neither vitamin D nor K impacted vitamin A uptake. Vitamin E significantly improved vitamin A uptake at medium and … Continue reading Fat-soluble vitamin competition
Two 2020 rodent studies investigated intervertebral disk degeneration, with the first on AGEs’ role: “This study evaluated the role of AGEs and RAGE in driving early intervertebral disk (IVD) degeneration processes in mice. Aging and diabetes are associated with increased low-back pain and IVD degeneration, yet causal mechanisms remain uncertain. AGEs: Accumulate in IVDs from … Continue reading Back pain and advanced glycation end products (AGEs)
“To every thing there is a season, and a time to every purpose under heaven: A time to break down, and a time to build up; A time to mourn, and a time to dance; A time to embrace, and a time to refrain from embracing; A time to keep silent, and a time to … Continue reading A time to speak
This 2021 human review subject was interactions of gut health and disease with brain health and disease: “Actions of microbial metabolites are key for appropriate gut-brain communication in humans. Among these metabolites, short-chain fatty acids (SCFAs), tryptophan, and bile acid metabolites / pathways show strong preclinical evidence for involvement in various aspects of brain function … Continue reading Gut and brain health
