The Adaptation-Maladaptation Framework of Aging
While a great deal is known about the ways in which old tissues differ from young tissues, there remains considerable room to theorize on how exactly aging is caused and progresses. Which manifestations are causative, and which downstream consequences, which mechanisms are important, which are side-effects or diversions. Theories of aging abound, alongside frameworks intended to steer thinking about aging. We stand in the opening years of a new era of medicine, in which the first rejuvenation therapies exist or are under development, senolytics that can clear senescent cells, alongside reprogramming strategies and potentia...

Fight Aging! Newsletter, September 11th 2023
This article reviews the current regulatory role of miR-7 in inflammation and related diseases, including viral infection, autoimmune hepatitis, inflammatory bowel disease, and encephalitis. It expounds on the molecular mechanism by which miR-7 regulates the occurrence of inflammatory diseases. Finally, the existing problems and future development directions of miR-7-based intervention on inflammation and related diseases are discussed to provide new references and help strengthen the understanding of the pathogenesis of inflammation and related diseases, as well as the development of new strategies for clinical interventi...

Q & A With Dylan Burnette: Muscle Cells, Cell Movement, and Microscopy
Courtesy of Dr. Dylan Burnette.
“We scientists know very little of what can be known—I find that invigorating,” says Dylan Burnette, Ph.D., an associate professor of cell and developmental biology at Vanderbilt University School of Medicine in Nashville, Tennessee. “Most people find it exhausting, but I’m comfortable with not knowing all of biology’s secrets.” In an interview, Dr. Burnette shared his lab’s work on muscle cells, the knowledge he hopes readers take away from his research, and some advice to future scientists about being comfortable being wrong.
Q: How did you first become interested in s...

A High Level Popular Science View of the Longevity Industry
The article I'll point out today is an entirely unremarkable, high level tour of the most discussed, most notable portions of the longevity industry and related research efforts. Twenty years ago, we'd all have been delighted to see the media both noticing translational aging research at all, and then actually taking seriously the prospect of treating aging as a medical condition. We've come a long way to now see summary discussions of work on the treatment of aging as business as usual, not really worth mentioning. Still, articles like this miss near all of the really interesting projects, and that is the way of high leve...

In conclusion, although the contribution of CRF to GrimAgeAccel and FitAgeAccel is relatively low compared to lifestyle-related factors such as smoking, the results suggest that the maintenance of CRF is associated with delayed biological ageing in older men.

Bridging the Representation Gap in Biomedical Research
“We hope that students come out of our program feeling like they’re part of a community. Many of us feel inadequate or struggle in some way during graduate school—it can be a challenging time. I want to build a community that our students can always come back to for support,” says Elana Ehrlich, Ph.D., the co-director of the Bridges to the Doctorate Research Training Program (B2D) at Towson University in Towson, Maryland, alongside Michelle Snyder, Ph.D..
The Towson B2D is one of several NIGMS-supported B2Ds, which are dedicated to developing a diverse pool of well-trained biomedical scientists who will transiti...

Evidence review: Physical exercise helps boost attention, cognitive flexibility and inhibitory control in children and adolescents with ADHD
Conclusions based on a single study –no matter how strong the study design and execution may be– are necessarily limited, however. This has led researchers to combine results from multiple studies using a statistical technique called meta-analysis so that more robust and reliable estimates of a treatment’s impact can be determined.
Meta-analyses also have limitations, however. Decisions made about which studies to include vs. exclude, how to adjust for potential biases in individual studies, etc., can lead different meta-analyses of the same issue to reach somewhat different conclusions, even when the studies examine...

This study aimed to investigate the association between frailty index and circulating CAP2 concentration in 467 community-dwelling older adults (median age: 79; range: 65-92 years). The selected robust regression model showed that circulating CAP2 concentration was not associated with chronological age, as well as sex and education. However, circulating CAP2 concentration was significantly and inversely associated with the frailty index: a 0.1-unit increase in frailty index leads to ~0.5-point mean decrease in CAP2 concentration. Furthermore, mean CAP2 concentration was significantly lower in frail participants (i.e., fr...

In conclusion, here, we demonstrate a novel mechanism for ESC-EVs to protect cells from senescence. However, whether ESC-EVs rejuvenate aged mice via miR-15b-5p and miR-290a-5p remains unknown. Next, we plan to use miR-15b-5p and miR-290a-5p antagonists while treating aged mice with ESC-EVs to further investigate the mechanism by which ESC-EVs resist aging in vivo.
