This 2014 fruit fly study found: “A biologically relevant event such as finding food under starvation conditions or being poisoned can drive long-term memory in a single training session.” I don’t think that we need to discover at these extremes, though, whether or not the finding has human applicability. We do know from the Dutch … Continue reading A biologically relevant event can drive long-term memory in a single training session
Three papers on boron, starting with a 2022 review: “Boron-containing compounds (BCC) have effects in the metabolism of living organisms. Information regarding effects and interaction of these compounds was compiled, and potential applications for treating human metabolic disorders was suggested. Dietary boron supplementation affects metabolism of calcium, magnesium, triglycerides, glucose, amino acids, reactive oxygen, nitrogen … Continue reading Is boron important to health?
Two 2022 papers, starting with a review of irisin: “This article is an overview of irisin generation, secretion, and tissue distribution. Its targeting of tissues or organs for prevention and treatment of chronic diseases is systematically summarized, with discussion of underlying molecular mechanisms. Irisin is an exercise-induced myokine expressed as a bioactive peptide in multiple … Continue reading The goddess of rainbows
Two papers on aging measurements, starting with a 2022 human study: “We collected longitudinally across the adult age range a comprehensive list of phenotypes within four domains (body composition, energetics, homeostatic mechanisms and neurodegeneration / neuroplasticity) and functional outcomes. We integrated individual deviations from population trajectories into a global longitudinal phenotypic metric of aging. We … Continue reading Variable aging measurements
Three 2022 papers on methylation epigenetic modifiers, starting with a human study focused on mitochondrial DNA non-CpG methylation involving nucleobases other than guanine (arginine, cytosine, or thymine): “We collected brain tissue in the nucleus accumbens and prefrontal cortex from deceased individuals without (n = 39) and with (n = 14) drug use, and used whole-genome bisulfite sequencing to cover … Continue reading Non-CpG methylation
Three 2022 papers of interest cited Sulforaphane: Its “Coming of Age” as a Clinically Relevant Nutraceutical in the Prevention and Treatment of Chronic Disease. Let’s start with a fairly straightforward analysis of blanching broccoli sprouts to produce sulforaphane: “We investigated the effect of blanching conditions to determine the optimal treatment that maximizes sulforaphane (SFN) content … Continue reading Blanching broccoli sprouts
Three 2022 papers, starting with a rabbit study of dietary supplements: “Adding native type II collagen (NC) to the combination of chondroitin sulfate (CS), glucosamine hydrochloride (GlHCl), and hyaluronic acid (HA) showed improvements on osteoarthritis progression. Disease progression was monitored at different time points using magnetic resonance imaging biomarkers, measurement of hyaluronic acid in synovial … Continue reading Supplement evidence and counter-evidence
Two 2022 papers from a clinical trial investigating dietary AGEs’ effects in middle-age people: “A 4-week diet low or high in AGEs has no effect on insulin sensitivity, secretion, or clearance; vascular function; or overall inflammation in abdominally obese but healthy individuals. These findings require validation in large prospective cohort studies and in populations with … Continue reading Green light for BBQ?
Two 2022 human studies on sRAGE, starting with one of hypoxia-related diseases: “The receptor for advanced glycation end products is found on endothelial and inflammatory cell surfaces. It binds to circulating advanced glycation end products, activating a proinflammatory protein cascade that contributes to systemic oxidative stress and inflammation. sRAGE is the soluble isoform of RAGE … Continue reading The soluble receptor for AGEs
This June 2022 review cited twenty 2022 papers for relationships between Parkinson’s disease and gut microbiota: “Clinical diagnosis of PD is based on typical motor symptoms, and novel diagnostic biomarkers have been developed such as imaging markers, and α-synuclein fluid and tissue markers. Multimorbidity of non-motor disorders heighten the risk of adverse outcomes for patients … Continue reading Gut microbiota therapy
Finishing a week’s worth of 2022 taurine research with two reviews of taurine’s brain effects: “We provide a overview of brain taurine homeostasis, and review mechanisms by which taurine can afford neuroprotection in individuals with obesity and diabetes. Alterations to taurine homeostasis can impact a number of biological processes such as osmolarity control, calcium homeostasis, … Continue reading Taurine week #7: Brain
Two 2022 rodent studies of taurine’s associations with long-term stress, starting with a chronic restraint stress model: “We show that chronic restraint stress can lead to hyperalgesia accompanied by changes in gut microbiota that have significant gender differences. Corresponding changes of bacteria can further induce hyperalgesia and affect different serum metabolism in mice of the … Continue reading Taurine week #6: Stress
It’s been a while since I curated taurine research. Read at least a week’s worth of 2022 papers last weekend. Let’s start with two studies that didn’t supplement with taurine, but found it was a biomarker. The first was a rodent study that treated a high fat diet with blood pressure medicine: “Non-alcoholic fatty liver … Continue reading Taurine week #1: Biomarkers
Three papers on betaine’s effects, starting with a 2022 review: “Rodent studies provide evidence that betaine effectively limits many diabetes-related disturbances. Betaine therapy improves glucose tolerance and insulin action, which is strongly associated with changes in insulin-sensitive tissues, such as skeletal muscle, adipose tissue, and liver. Betaine supplementation positively affects multiple genes, which expression is … Continue reading Betaine and diabetes
Two 2022 studies, starting with “Increasing bound antioxidant compounds through their reaction with soluble phenolic compounds”: “Wheat, oat, rye, and rice bran samples were reacted with different concentrations of beverages (green tea infusion, black tea infusion, espresso, and red wine) rich in various soluble phenolic compounds. Green tea infusion was found to be the most … Continue reading Food combination effects
