In this study, oral administration of Lactococcus lactis strain H61 to senescence-accelerated mice was linked to reduced bone density loss, less skin ulcer incidence, and reduced hair loss, along with altered immune responses.

This review discusses the relationship between estrogen deficiency and skin aging in postmenopausal women, noting potential benefits of estrogen use on skin collagen and elasticity, but reports no new clinical results.

This study found that conditioned media from epidermal progenitor cells improved skin aging signs in a clinical trial and protected fibroblasts from oxidative stress in vitro.

This review discusses the role of defensin peptides in stem cell activation for potential skin rejuvenation therapies and reports no new clinical findings, emphasizing the need for further studies.

The document concludes that there are still unknowns about the effectiveness, risks, and detection of performance-enhancing drugs, and doping remains a challenge.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This study found that berry extracts, especially black raspberry extract, may have anti-aging effects due to their high antioxidant activities.

This study developed a new method for detecting 30 hormones in anti-aging functional foods, demonstrating good sensitivity and reliability, and identified seven hormones in four out of 14 samples tested.

This study found that honokiol inhibits enzymes related to testosterone degradation in vitro, suggesting its potential as a lead compound for developing antiaging bioactive ingredients for men.

This study suggests that hydroxypinacolone retinoate (HPR) may be an effective alternative to tretinoin for anti-aging skin treatments, offering similar collagen production benefits without increased skin irritation.

This review discusses the biological and cosmetic aspects of hair aging and reports no new clinical results; it highlights current treatments and future research directions to address both aging factors.

This study found that a combination of five medicinal plants traditionally used in Chinese medicine significantly improved skin repair and delayed aging markers in laboratory models, suggesting synergistic anti-aging effects over individual ingredients.

This study found that oral intake of choline-stabilized orthosilicic acid (ch-OSA®) significantly improved hair, skin, and nail health in the Indian population, with no reported side effects.

In this study, the authors found that a botanical extract with anti-inflammatory and anti-oxidative properties stabilized hair loss and preserved natural hair pigmentation and strength over six months.

This review discusses strategies for developing semi-solid topical generic products to match the quality of reference-listed drugs, using concepts like quality by design and reverse-engineering, but reports no new results.

This article reviews current understanding of dermal fibroblasts' structure and function, highlighting their crucial role in connective tissue formation and repair, which is important for selecting effective treatments for age-related skin changes.

This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This computational study developed a regulatory model linking key genes and miRNAs to cardiac senescence, validated by connecting 94% of these elements to existing cardiac aging research.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This study indicated that while testosterone replacement in older men with low testosterone increases muscle mass and strength and reduces fat, its effects on physical function, disability, falls, or fractures remain unclear.

This review outlines various clinical methods for assessing ageing skin and discusses their application in supporting the efficacy claims of anti-ageing treatments, but it reports no new clinical results.

This review discusses genome maintenance mechanisms critical for preventing age-related diseases by preserving stem and progenitor cell potential, but reports no new empirical findings.

This study found that pharmacological inhibition of sex steroid synthesis impacts pathogenic processes in traumatic brain injury in a sex-specific manner, with distinct effects of letrozole and finasteride on molecular and neurological outcomes.

This article updates the process of care model for evaluating erectile dysfunction, emphasizing comprehensive evaluation and a combination of pharmacotherapy and counseling tailored to patient dynamics.

This article reviews the therapeutic use of carnitine derivatives for re-establishing mitochondrial functionality in aging and reports no new clinical results.

The review synthesized evidence from 144 articles to assess the effectiveness and potential side effects of surgical and non-surgical techniques for facial rejuvenation.

This study found that age-related changes in scalp dermal fibroblasts, including increased MMP-1 and reduced ECM components, may significantly affect the hair follicle environment and contribute to hair aging.

This study investigated novel genetic tools to manipulate hair follicle compartments in mice and found that altering dermal papilla genes can significantly impact hair pigmentation.

This study found that gypenosides from Gynostemma pentaphyllum increased procollagen synthesis in vitro and reduced periorbital wrinkles by about 14% in a clinical trial with 24 women.

This source redefines anti-aging medicine as "precision healthspan pharmacology," suggesting that rather than just treating diseases or accepting aging, pharmacology should focus on expanding functional capacity across various health domains, while emphasizing the importance of fundamental physiological and psychosocial health factors.
