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: Women; or Supplementing 50 mg/d; or Undergoing intervention for > 12 weeks; or Without an underlying comorbidity; or Over the age of 60 years. DHEA supplementation led … Continue reading Take responsibility for your one precious life – DHEA

Take responsibility for your one precious life – Trained innate immunity

This 2020 review subject was the normal progression of our immune systems: “Age-related alterations in the immune system result in high susceptibility to infections, increased risk of hospitalization and mortality. Defects in adaptive immunity underlie the markedly low vaccine efficiency in the elderly. Despite reduced cellular functions, a systemic increase in inflammatory markers, so-called inflammaging, … Continue reading Take responsibility for your one precious life – Trained innate immunity

Take responsibility for your one precious life – β glucan

From the main page of https://www.betaglucan.org/, a compilation for researchers: “Beta Glucan extracted from yeast cell wall, can be a potent immune response potentiator and modulator. A common test to determine a glucan’s immune response potentiation effectiveness is the measure of the degree to which a glucan increases the nitric oxide burst, a pathogen killing … Continue reading Take responsibility for your one precious life – β glucan

Take responsibility for your one precious life – Vitamin D3

Where to start among 6,489 studies and reviews published during the past five years, results from a PubMed search of “dihydroxyvitamin D3.” How about: “Vitamin D plays a fundamental role in body calcium and phosphorous homeostasis, ensuring proper functioning of the skeletomuscular system. Pleiotropic activities include: Anti-inflammatory and immunomodulatory properties (predominantly downregulation of adaptive and … Continue reading Take responsibility for your one precious life – Vitamin D3

Take responsibility for your one precious life – Zinc

This 2020 review highlighted earlier clinical data on zinc: “Zinc is known to modulate antiviral and antibacterial immunity and regulate inflammatory response. Zinc possesses anti-inflammatory activity by inhibiting NF-κB signaling and modulation of regulatory T-cell functions. The most critical role of zinc is demonstrated for the immune system. Zinc regulates proliferation, differentiation, maturation, and functioning … Continue reading Take responsibility for your one precious life – Zinc

Immune system aging

This 2021 review by three coauthors of Take responsibility for your one precious life – Trained innate immunity cast a wide net: “Non-specific innate and antigen-specific adaptive immunological memories are vital evolutionary adaptations that confer long-lasting protection against a wide range of pathogens. However, these mechanisms of memory generation and maintenance are compromised as organisms … Continue reading Immune system aging

Human agency vs. brain dysfunction

This 2021 human study used epigenetic clock technology to assess chronic inflammation as a driver of cognitive decline through its effects on brain structure: “An epigenetic measure of C-reactive protein (DNAm CRP) was assembled for each participant. We found that higher inflammatory burden, indexed by DNAm CRP scores, associated with poor cognitive and neuroimaging brain … Continue reading Human agency vs. brain dysfunction

Reinforce your immune memory every day

Three papers on trained immunity, with the first a 2021 review: “Trained immunity is realized by epigenetic reprogramming of cells, primarily monocytes/macrophages and natural killer cells, and is less specific than adaptive immunity. It may cross-protect against other infectious agents. Various actions of trained innate immunity on precursor cells have a strong potential for therapeutic … Continue reading Reinforce your immune memory every day

Trained immunity mechanisms

This 2021 cell study investigated how inflammatory memory is established, maintained, and recalled: “Cells retain a memory of inflammation that equips them to react quickly and broadly to diverse secondary stimuli. Temporal, dynamic changes to chromatin accessibility, histone modifications, and transcription factor (TF) binding occur during inflammation, post-resolution, and in memory recall following injury. Epigenetic … Continue reading Trained immunity mechanisms

Choosing your gut immune response

This 2021 paper reviewed evidence for immune system effects associated with specific gut areas: “The intestinal immune system must not only contend with continuous exposure to food, commensal microbiota, and pathogens, but respond appropriately according to intestinal tissue differences. The entire intestine, inclusive of its lymph nodes, is considered a immunosuppressive organ overall compared to … Continue reading Choosing your gut immune response

An IBD trigger?

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?

Back pain and advanced glycation end products (AGEs)

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)

Part 2 of Eat broccoli sprouts for your hearing

Went to a free hearing test at Costco this week. Results weren’t significantly different than those from a doctor’s office 2.5 years ago: Didn’t have many expectations, other than I’d be given a hard sell to buy hearing aids by a technician on commission. A young woman used several sales techniques which I was prepared … Continue reading Part 2 of Eat broccoli sprouts for your hearing

Are overdosed rodent studies relevant to humans?

I partially read more than a dozen studies this week of overdosed rodents producing p < .05 significant results. Net effect was to thwart the purpose of rodent studies – to help humans. The latest came from search term “SIRT1” “DHEA” 2021 after I read a 2021 study Dehydroepiandrosterone protects against acetaminophen-induced liver damage in … Continue reading Are overdosed rodent studies relevant to humans?

Choosing your future with β-glucan

This 2020 rodent study investigated yeast cell wall β-glucan effects on bacterial infections: “β-glucan is a potent inducer of epigenetic and functional reprogramming of innate immune cells, a process called trained immunity, resulting in an enhanced host response against secondary infections. We investigate whether β-glucan exposure confers protection against pulmonary Mycobacterium tuberculosis (Mtb) infection. β-glucan … Continue reading Choosing your future with β-glucan
