Lowering US pneumonia death counts to increase COVID-19 death counts

To follow up CDC directs the US to attribute deaths from other causes to COVID-19, my sending its information to Tucker Carlson yesterday morning may have contributed to the information being broadcast nationally yesterday evening. The transcript at Tucker Carlson: Possible That Doctors Are Classifying Conventional Pneumonia Deaths As COVID Deaths, Increasing The Count included: … Continue reading Lowering US pneumonia death counts to increase COVID-19 death counts

How much sulforaphane is suitable for healthy people?

This post compares and contrasts two perspectives on how much sulforaphane is suitable for healthy people. One perspective was an October 2019 review from John Hopkins researchers who specialize in sulforaphane clinical trials: Broccoli or Sulforaphane: Is It the Source or Dose That Matters? Since these researchers didn’t give a consumer-practical answer, I’ve presented a … Continue reading How much sulforaphane is suitable for healthy people?

Train your immune system every day!

This 2019 US review subject was β-glucan: “β-1,3-Glucans (hereafter referred to as glucan) are natural molecules able to significantly improve our health. In human studies, the tested (and suggested) daily dose remains in the range of 100–500 mg for stimulation of the immune system, whereas for a decrease in cholesterol levels a daily dose of … Continue reading Train your immune system every day!

Effects of advanced glycation end products on quality of life and lifespan

This 2018 Chinese review concerned advanced glycation end products (AGE) mobility interventions: “Only a limited number of studies have focused on measuring the effects of low AGEs levels or AGEs inhibitors on mobility, although many observational human studies and in vitro studies have reported the correlation of AGEs with and the contribution of AGEs to … Continue reading Effects of advanced glycation end products on quality of life and lifespan

A trio of epigenetic clock studies

We’ll start with a 2018 epigenetic clock human study from Finland: “We evaluated the association between maternal antenatal depression and a novel biomarker of aging at birth, namely epigenetic gestational age (GA) based on fetal cord blood methylation data. We also examined whether this biomarker prospectively predicts and mediates maternal effects on early childhood psychiatric … Continue reading A trio of epigenetic clock studies

Gene therapy by DNA methylation using CRISPR-Cas9

This 2016 Croatian human cell study was a proof-of-concept to induce specific DNA methylation of two genes: “In this work we have created and characterized a novel CRISPR-Cas9-based epigenome editing tool, the dCas9-DNMT3A, which enabled targeted and specific CpG methylation at the promoter of two loci, the BACH2 and the IL6ST. We have demonstrated the … Continue reading Gene therapy by DNA methylation using CRISPR-Cas9

Problematic research into epigenetic effects of paternal stress on male offspring

This 2016 Chinese rodent study and its accompanying commentary Don’t stress dad — it’s bad for your kids’ health were caught up in an agenda. The first problem I noticed was that the hyperglycemic effects found only in the male offspring weren’t consistently labelled as sex-specific. Try to find that fact in the paywalled commentary … Continue reading Problematic research into epigenetic effects of paternal stress on male offspring

Mitochondria interface genetic/epigenetic responses to psychological stress

This 2015 Pennsylvania rodent study found: “Mitochondria can regulate complex whole-body physiological responses, impacting stress perception at the cellular and organismal levels. Mitochondrial dysfunctions altered the hypothalamic–pituitary–adrenal [HPA] axis, sympathetic adrenal–medullary activation and catecholamine levels, the inflammatory cytokine IL-6, circulating metabolites, and hippocampal gene expression responses to stress. Stress-induced neuroendocrine, inflammatory, metabolic, and transcriptional responses … Continue reading Mitochondria interface genetic/epigenetic responses to psychological stress

If research treats “Preexisting individual differences” as a black box, how can it find causes for stress and depression?

This 2014 research studied both humans and rodents to provide further evidence on the physiology of defeat. The researchers demonstrated that with mice: “Bone marrow transplants of stem cells that produce leucocytes lacking IL-6 (the cytokine interleukin 6) or when injected with antibodies that block IL-6 prior to stress exposure, the development of social avoidance … Continue reading If research treats “Preexisting individual differences” as a black box, how can it find causes for stress and depression?
