The function of the dorsal ACC is to monitor pain in survival contexts

This 2015 California human study was of the dorsal anterior cingulate cortex (dACC): “No neural region has been associated with more conflicting accounts of its function than the dACC. The best psychological description of dACC function was related to pain processing—not executive, conflict, or salience processing. We conclude by considering that physical pain may be … Continue reading The function of the dorsal ACC is to monitor pain in survival contexts

What do we know about human aging from mouse models?

Here is a 2021 rodent study and relevant parts from 3 of its 26 citing papers: “A long line of evidence has established the laboratory mouse as the prime model of human aging. However, relatively little is known about detailed behavioral and functional changes that occur across their lifespan, and how this maps onto the … Continue reading What do we know about human aging from mouse models?

Broccoli sprouts activate the AMPK pathway, Part 4

Today someone viewed the 2020 Part 3 of Broccoli sprouts activate the AMPK pathway which lacked citations at the time. Checking again, here are three citing 2022 papers, starting with a review: “Nrf2 is an important transcription factor that regulates expression of a large number of genes in healthy and disease states. Nrf2 regulates expression … Continue reading Broccoli sprouts activate the AMPK pathway, Part 4

Eat broccoli sprouts for longevity

This 2022 rodent study investigated effects of broccoli sprouts intake on health and longevity: “The objective of this study was to assess effects of long-term broccoli sprouts (BrSp) feeding on longevity in rats, as well as on cardiometabolic health parameters. Twelve-week-old Long-Evans rats were randomized to control or BrSp groups. Broccoli seeds were sprouted for … Continue reading Eat broccoli sprouts for longevity

How to measure biological age?

As mentioned in Week 127, I had biological age measured earlier this month, and received five reports two days ago on Sunday. Part of the company’s process is to follow up their reports (intrinsic aging, immune aging, pace of aging, telomere length, weight loss) with a consulting session to review and interpret, which lasted an … Continue reading How to measure biological age?

Minds of their own

It’s the weekend, so it’s time for: Running errands? Watching sports? Other conditioned behavior? Or maybe broadening our cognitive ability with Dr. Michael Levin’s follow-ups to his 2021 Basal cognition paper and 2020 Electroceuticals presentation with a 2022 paper and presentation starting around the 13:30 mark: “A homeostatic feedback is usually thought of as a … Continue reading Minds of their own

An inflammation clock

Here are six 2022 papers that either cited the second study of Variable aging measurements, or provided further evidence for its findings. Let’s start with a citing study: “This study aimed to investigate expression patterns and prognostic values of the inflammatory aging clock (iAge) in glioblastoma (GBM), and its relations with stem cells. Similar to … Continue reading An inflammation clock

If you lose mobility, you lose cognitive function

This 2022 human study used four epigenetic clocks to assess aging: “This cohort study was a secondary analysis of 3 Women’s Health Initiative (WHI) ancillary studies among 1813 women eligible to survive to age 90 years by end of study period. The study found that increased epigenetic age acceleration (EAA) as measured by 4 epigenetic … Continue reading If you lose mobility, you lose cognitive function

Variable aging measurements

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

The soluble receptor for AGEs

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

Taurine week #7: Brain

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

Taurine week #3: Organs

Three 2022 papers investigated taurine’s effects on organs, starting with a rodent study of sepsis: “Sepsis usually causes multiple organ dysfunctions and high mortality. Pathogenesis of sepsis is thought to be driven by hyperactive inflammation following pathogen invasion. If the immune system fails to eradicate pathogens, immune homeostasis is disturbed, leading to an overwhelming inflammation … Continue reading Taurine week #3: Organs

A healthspan improvement

Two 2022 publishments, starting with an excerpt from an informative interview with the Director of one of the three Interventions Testing Program centers: “A paper submitted this week is one in which we tried a combination of rapamycin plus acarbose. Rapamycin works very well in male and female mice, while acarbose works significantly in both … Continue reading A healthspan improvement

Vitamin D and pain

This 2022 human study investigated epigenetic clock associations: “We assessed the potential relationship of Vitamin D’s effects on pain intensity and disability through associations in epigenetic aging in individuals with and without knee osteoarthritis (KOA). We hypothesized that associations between Vitamin D levels with pain intensity and interference in persons with KOA would be significantly … Continue reading Vitamin D and pain
