Unity Biotechnology Demonstrates Again that Localized Use of Senolytics Is Not So Great
Most of the research relevant to the question of whether localized clearance of senescent cells can effectively treat age-related conditions has taken place in the context of osteoarthritis. While adding senescent cells to a joint is sufficient to provoke the onset of osteoarthritis, clearing senescent cells from only the joint region is not sufficient to produce significant patient benefits. The present consensus is that the senescent cells present in the rest of the body are producing a significant contribution by their signaling: those cells may be more distant, and their contributions thus more dilute, but there are a ...

The Tradeoff of Working with Short-Lived Laboratory Species
It is cheaper and faster to study aging - and potential approaches to treat aging - in short-lived species. The disadvantage is that much of what is learned and achieved will be irrelevant to aging as it occurs in longer-lived species such as our own. The response to calorie restriction, an upregulation of cellular housekeeping mechanisms that lengthens life, fortunately evolved early on in the development of life, and the biochemistry is surprisingly consistent even across widely divergent species. Thus much can be learned of it in lower animals with short life spans. Unfortunately, it turns out that this class of interve...

This study has potentially significant implications in the field of OA as it provides a novel strategy for OA treatment. A Vicious Cycle of Heart Failure and Dementia https://www.fightaging.org/archives/2023/03/a-vicious-cycle-of-heart-failure-and-dementia/ The end of life is not pretty. The body is a failing machine of many complex essential parts, and the failures cascade and feed into one another as it breaks down. There is pain, loss of capacity, loss of the self as the brain runs down. There is a tendency to paper over the ugly reality in public discussion, to not talk about the facts of the matter...

What do people want from pain management?
The short answer is often “take my pain away” – and we’d be foolish to ignore the impact of pain intensity on distress and disability. At the same time there’s more than enough research showing that if treatment only emphasises pain intensity (1) it may not be achievable for many, especially if we take into account the small effect sizes on pain intensity from exercise, medications and psychological therapies; and (2) even if pain is reduced, it may not translate into improvements in daily life. The slightly more complex answer lies behind the desire to “take my pain away.” We n...

This study investigated whether taller Polish adults live longer than their shorter counterparts. Data on declared height were available from 848,860 individuals who died in the years 2004-2008 in Poland. To allow for the cohort effect, the Z-values were generated. Separately for both sexes, Pearson's r coefficients of correlation were calculated. Subsequently, one way ANOVA was performed. The correlation between adult height and longevity was negative and statistically significant in both men and women. After eliminating the effects of secular trends in height, the correlation was very weak (r = -0.0044 in men and ...

Aging as a Disease: a Zoo Contains Animals, But is Not Itself an Animal
The author of today's open access commentary is quite prolifically opinionated on the topic of mTOR and its status as a central pillar of programmed aging, particularly the hyperfunction version of programmed aging theories. Nonetheless, he sometimes has interesting things to say, as is the case here on the topic of whether aging is a disease. A great deal of ink has been spilled of late on the question of whether or not aging is a disease. This is the case not because everyone suddenly developed an interest in semantics, but rather because it directly affects the regulation of medical development, and thus the flow of fun...

This study explored the association between tap drinking water and longevity in Cilento, Italy, to understand whether trace elements in local drinking water may have an influence on old, nonagenarian, and centenarian people and promote their health and longevity. Data on population and water sources were collected through the National Demographic Statistics, the Cilento Municipal Archives, and the Cilento Integrated Water Service. Ordinary least squares (OLS) regression and a geographically weight regression (GWR) model were used to study the spatial relationship between the explanatory and outcome variables of long...

Extracellular Matrix Stiffening Contributes to Cartilage Aging and Osteoarthritis
Age-related changes in the structure of the extracellular matrix that surrounds and supports cells are not as well studied as changes in cell behavior. Nonetheless, there is plenty of evidence for changes in the extracellular matrix to negatively affect tissue function. Cells create and maintain the matrix, but the state of the matrix in turn influences cells, and over time is affected by more than just cell behavior. Metabolic processes can alter and fragment elastin, cross-link collagen molecules, and so forth. Cross-linking of matrix molecules occurs with age as a byproduct of the normal operation of metabolism, ...

A Tale of Tails: How Reptile Regeneration Could Help Humans
Dr. Thomas Lozito. Credit: Chris Shinn for USC Health Advancement Communications. “I’ve always been interested in science and in lizards. I got my first pet lizard when I was around 4 years old, and it was love at first sight,” says Thomas Lozito, Ph.D., who now studies the creatures as an assistant professor of orthopaedic surgery, stem cell biology, and regenerative medicine at the University of Southern California (USC) in Los Angeles. During his childhood, Dr. Lozito turned his parents’ house into a “little zoo” of lizards and amphibians. He sneaked lizards into his dorm room as a college student at Jo...

In conclusion, circulating monocytes in older adults exhibit increased expression of activation, adhesion, and migration markers, but decreased expression of co-inhibitory molecules. MERTK Inhibition Increases Bone Density via Increased Osteoblast Activity https://www.fightaging.org/archives/2022/12/mertk-inhibition-increases-bone-density-via-increased-osteoblast-activity/ Bone density results from the balance of constant activity on the part of osteoblasts and osteoclasts, the former building bone, the latter breaking it down. With advancing age, the balance of activity shifts to favor osteoclasts, pro...

A Popular Science View of the Development of Senolytic Therapies
Over the last decade, an increasing diversity of research groups and companies are working towards the clinical use of senolytic therapies to reverse aspects of aging in older patients by clearing harmful senescent cells. Of the early senolytic therapies, the dasatinib and quercetin combination is the only one with published data in human clinical trials showing clearance of senescent cells. This treatment is in fact easily accessible to self-experimenters, and even being prescribed off-label by more adventurous physicians. The biotech industry is working to produce a next generation of (probably) better approaches, and ob...
