Protein NEDD4 may protect disc cells from aging and cell death in a lab test
Researchers grew disc cells in a dish with an inflammation signal. Boosting NEDD4 eased aging and cell death, and it broke down another protein called PTEN. More tests in living animals and more checks are still needed.
Uterine function and reproduction aging. I. Molecular and structural alterations associated with impaired decidualization in aged mouse uteri.
Reproductive aging is associated with reduced fertility and increased risk of adverse pregnancy outcomes, including miscarriage, placental dysfunction, and fetal growth restriction.
Home exercise may change muscle in people with kidney disease
A small trial found changes in muscle blood vessels and fewer fibrosis-linked cells after 12 weeks of home exercise. Only 25 people took part, so this does not prove the exercise caused lasting muscle benefits.
Hydroxyproline with amino acids extended worm lifespan in lab tests
Researchers gave worms hydroxyproline plus three amino acids and saw longer life and better health markers. This was tested under set lab conditions, so it does not show the same effect in people.
Matched Plasma and Tissue Proteomics Reveal the Selective Nature of Circulating Biomarkers of Human Aging
Aging is systemic, yet how circulating proteins reflect molecular aging within solid tissues remains unclear.
Light mask and cream study on skin aging in women
Skin samples and 50 women used a light mask and cream for weeks, and skin looked better. This study was small and early, so it does not prove the products work for everyone.
The Impact of Aging on the Tongue Proteome.
The tongue is a highly important, multifunctional, and complex organ in human physiology. It is critical for digestion, speech, immune surveillance, and sensory perception, playing a dynamic role in daily life.
Senolytic drug reduced skin scarring after radiation in mice
Researchers studied how radiation causes skin to stiffen and scar. They found a loop between aging cells and immune cells that seems to drive it. The drug ABT-263 reduced scarring in these mice, but this does not show it works in people.
Proteomic Features and Association Analysis of Late-Onset Depression Based on Behavioral Factorial Analysis and Proteomics.
Late-onset depression (LOD) is a common subtype of depression in the elderly, characterized by high disability and recurrence rates, along with poorly understood biological correlates, posing a serious threat to the…
Exosome-Based Therapies for Skin Aging: Sources, Mechanisms, and Evidence from Preclinical and Clinical Studies.
Skin aging is an inevitable physiological process co-driven by endogenous genetic programs and exogenous environmental factors, characterized by the progressive deterioration of skin structure and function, which…
Enzymatic extracellular matrix remodeling in ex vivo slices of aged myocardium
Cardiac aging is accompanied by extracellular matrix (ECM) remodeling and increased myocardial stiffness, which may contribute to age-associated functional decline.
Marine-Derived Injectable Hydroxybutyl Chitosan with Tunable Thermoresponsive Properties and Potential Anti-aging Applications.
Skin aging, largely driven by oxidative stress, leads to fibroblast senescence, deterioration of the extracellular matrix, and impaired regenerative capacity; however, effective biomaterial-based interventions remain…
Methylmalonic Acid in Skeletal Aging and Osteoporosis: Linking Vitamin B12 Metabolism to Mitochondrial Dysfunction.
Methylmalonic acid (MMA) is a functional marker of vitamin B12 insufficiency and an emerging metabolic factor associated with skeletal aging and osteoporosis.
Gonad collagens help worms keep eggs healthy as they age
Scientists found that certain collagens in worm reproductive tissue helped keep eggs and embryos in good shape. Turning these collagens down sped up reproductive decline, but it does not show the same is true in people.
Sea cucumber tiny particles studied as possible skin aging tools
This review gathers what is known about tiny particles from sea cucumbers and their possible use in skin care. It says the ideas still need tests in people before any claims can be confirmed.
Plant extracts studied for effects on aging skin cells in a preprint
Researchers tested plant extract mixes on aged skin cells and skin samples in a lab. This is an early preprint, not yet checked by other scientists, so it does not show these mixes help real skin.
Inflammation-Responsive Baicalin-Delivering Glycocalyx-Mimetic Hydrogel-Functionalized Bioprosthetic Valve for Antithrombosis and Immunomodulation.
Valvular heart disease (VHD), a prevalent age-associated condition associated with high mortality, is primarily treated by prosthetic valve replacement.
Review of copper peptide GHK-Cu studies finds many lab results but few human trials
Researchers read 64 studies on GHK-Cu, a copper-linked peptide, and found much lab and animal work. They say well-designed human trials using microneedles are still needed.
Review of a copper peptide used in skin treatments
Researchers reviewed 20 studies on GHK-Cu, a copper peptide, for skin and beauty uses. Most were lab or animal studies, and only two were human trials, so more strong testing is still needed.
Effects of Supplementation in Masters Athletes and Older Adults: A Narrative Review.
Supplementation use in athletes is common and increasing in popularity, especially for adults seeking improvements in athletic performance.
