This source critically examines Bruce Ames's influential contributions to biochemistry, particularly his theories on oxidative stress and mitochondrial DNA damage in aging, while acknowledging current challenges to his work and highlighting his lasting impact on the fields of mutagen screening and public health.

In this study, PDO, PLLA, and PCL thread implants in ageing rat skin did not alter MMP1 gene expression but maintained collagen levels similar to young skin without UV-B exposure, suggesting possible benefits for skin collagen but not gene expression modification.

This review reports significant advancements in plastic surgery using stem cell therapies for aesthetic and reconstructive applications, including grafting and wound healing, though it underscores the need for continued research to address regulatory, ethical, and standardization issues.

This review explores how cell and mouse models have contributed to understanding the mechanisms of human aging, particularly focusing on Hutchinson-Gilford Progeria Syndrome, and reports no new clinical results.

In this study, researchers found that correcting the HGPS mutation with Adenine base editing partially rescued accelerated skin cell differentiation and reduced cell death in patient-derived stem cells.

More research is needed to understand hair aging and develop effective treatments.

This review discusses the role of estrogen deficiency in post-menopausal skin aging and wound healing, highlighting opportunities for developing estrogen receptor-targeted therapies and reports no new clinical results.

This study found that mitochondrial dysfunction in the epidermis contributes to aging-related changes in hair follicles among mice, with aged mice showing reduced hair density and delayed regrowth, suggesting that maintaining mitochondrial function may help prevent age-related organ decline.

This review discusses the identification and characteristics of melanocyte stem cells, emphasizing their role in hair pigmentation, greying, and skin repigmentation, but reports no new research findings.

This study discusses how redox imbalance, specifically through reduced Insulin-like Growth Factor-1 mediated by the transcription factor JunB and sphingolipid metabolism changes, contributes to skin aging by depleting stem cell pools and altering the extracellular matrix, ultimately impacting skin integrity and function.

This article discusses potential links between male balding, specifically androgenic alopecia, and severe COVID-19, suggesting that balding may serve as a biomarker for identifying higher-risk patients, but it reports no new experimental findings.

In this study, researchers found that deleting the ATR gene in adult mice led to signs of premature aging and reduced capacity for tissue renewal.

This review analyzed 12 clinical studies on extracellular vesicle therapies, finding potential benefits for skin aging, acne scars, alopecia, and wound healing, but highlighted significant challenges like production standardization and lack of large-scale studies.

This study suggests that increased Wnt signaling may cause melanocyte stem cell exhaustion, leading to hair graying in aged mice by promoting excessive differentiation of melanocytes.

This review suggests that a dual treatment approach using Nourella® cream with nano-encapsulated Retilex-A® and per-oral Vercilex® tablets may effectively improve skin thickness, elasticity, and overall rejuvenation in aging skin, as shown in interventional studies.

This study highlights the critical role of mitochondria in skin aging and wound repair, suggesting that targeted interventions such as antioxidants, NAD⁺ boosters, and NRF2-based therapies may enhance mitochondrial function and improve cutaneous health.

This study found that Polygoni Multiflori Radix (PMR) reduced collagenase and elastase activity after UVB damage in fibroblasts, suggesting potential anti-aging properties for cosmetic use.

This review evaluates the anti-aging properties of TSG from He shou wu, finding it may protect against age-related diseases through multiple mechanisms, though further research is needed for clinical application.

This study developed a gas-propelled microneedle patch with puerarin/quercetin nanoparticles, which demonstrated improved hair-regenerating effects in an androgenetic alopecia mouse model by increasing drug delivery, alleviating oxidative stress, promoting angiogenesis, and rejuvenating senescent cells.

This review discusses the multiple factors contributing to skin aging, including cellular changes and environmental influences, and highlights its recognition as a disease with significant implications beyond cosmetic concerns, without reporting new research results.

This research abstract provides no results, focusing on the equal contributions of the authors in the field of molecular, cellular, and developmental biology from Yale University.

This review highlights the potential of coffee silverskin's bioactive compounds in combating skin aging and related conditions, suggesting it as a promising natural ingredient for cosmetics due to its antioxidant, anti-inflammatory, and anti-aging properties.

This study found that the small molecule honokiol may protect against inflammation, collagen breakdown, and cell damage caused by cigarette smoke in skin cells cultured in vitro.

This review highlights the role of the receptor TLR4 in cellular aging and age-related diseases, suggesting it as a potential therapeutic target due to its contribution to persistent inflammation and symptom regulation in these conditions.

This review discusses the role of telomere length dynamics in hair follicle biology and reports no new clinical findings, emphasizing the need for further research in humans.

This review explores the potential benefits of platelet-rich plasma for anti-aging and tissue regeneration, especially in orthopedic applications like osteoarthritis, but it reports no new clinical results.

This article reviews the functions and locations of skin stem cells and their role in regeneration and differentiation, relating age-associated skin changes to decreased stem cell functionality; it reports no new experimental findings.

This review critically examines scientific evidence on the health benefits of rosemary bioactives, finding potential in managing age-related diseases and skin aging conditions, and discusses their application in functional foods and aromatherapy, along with associated safety concerns.

This review discusses the processes of melanocyte stem cell quiescence and activation, focusing on their interaction with hair follicle stem cells, and highlights current research on hair graying mechanisms; it reports no new results.

In this study on mice, elevated IGF-1 levels in the skin were linked to premature aging of hair follicles, but interventions like reducing IGF-1 or using senolytic treatments helped restore stem cell health and counteract aging effects.
