This review introduces a framework to integrate bioinspired conductive materials and advanced 3D/4D printing in regenerative medicine for dynamic, responsive tissue regeneration, emphasizing the potential of smart scaffolds to adapt to physiological cues.

This study highlights the potential of medicinal plants like Rubus vulgaris and Plantago major as sources for skin disorder treatments due to their bioactive compounds' antioxidant, anti-inflammatory, and antimicrobial effects.

This study found that regular yoga practice could benefit women with PCOS by improving hormonal balance, mitochondrial health, oxidative stress, and inflammation, while also reducing depression symptoms, suggesting yoga as a supportive therapy for managing PCOS.

This study found that cultured foreskin is not suitable for studying H2A.J-related tissue changes during radiation-induced dermatitis due to existing high H2A.J expression and cytokine secretion even without irradiation.

This review explores how recombinant protein hydrogels, employing molecular engineering and crosslinking strategies, offer advanced applications in regenerative medicine by mimicking extracellular matrix dynamics and providing enhanced mechanical, environmental, and biological properties.

This review article highlights the potential of mesenchymal stem cells, their exosomes, and non-coding RNAs in repairing aging skin tissues due to their ability to secrete beneficial compounds, suggesting their promising role in photoaging treatment without causing immune rejection or granuloma formation.

This study suggests that women with polycystic ovary syndrome may have an increased risk of COVID-19-related cardiac and renal complications, and that weight loss through lifestyle changes could help reduce these risks.

This review discusses the potential antiaging effects of Chinese herbal medicines and suggests their role in regulating aging-related genes through various signaling pathways; it reports no new clinical results.

This review discusses the fundamental hallmarks of aging as they relate to skin aging and highlights the prominent roles of oxidative damage and the extracellular matrix in photoaging, reporting no new results.

This study found that expression of GDNF and GFR α-1 proteins in human skin decreases with age, particularly in the epidermis, suggesting that their signaling pathways may be altered as people grow older.

This study reported that atelocollagen enhances collagen synthesis and reduces oxidative stress in aged skin by increasing glycine uptake through GlyT1, resulting in improved skin elasticity and collagen density in aged mice, with effects superior to glycine alone.

This review covers red light Transcranial LED therapy for hippocampal memory impairment in aging and Alzheimer's but reports no clinical results, highlighting a need for further research into its mechanisms and effects.

In this study, researchers found that the management of alopecia areata in Poland is inadequate, despite following international guidelines, due to limited access to advanced treatments and insufficient use of severity assessments and psychosocial support.

The study found that enhancing quercetin bioavailability with EubioQuercetin may amplify its anti-aging effects in mice by modulating the gut microbiota and improving intestinal barrier function.

This review summarizes current knowledge on succinic acid's applications in cosmetics and aesthetic dermatology, highlighting its potential benefits such as inflammation modulation and collagen production, although most supporting studies are small or preliminary, indicating a need for further research to validate these uses.

This paper reviews advancements in 3D human skin models using bioprinting, organoid, and organ-on-a-chip technologies, noting improvements in physiological realism through vascularization and multi-omics data, but also highlighting challenges such as cost and lack of standardization that hinder clinical adoption.

In this study, researchers found that significant transcriptomic changes occur in the skin of Dezhou donkey foals as they age from newborns to one year old, involving gene expression shifts that may enhance skin barrier function and hair follicle development, while reducing collagen synthesis.

This study explored a mechanism for making Turing pattern formations more predictable and robust by isolating pattern modes to prevent their sensitivity to initial conditions, which can lead to different outcomes from minor initial changes.

This study examined dermal papilla cells from hair follicles, finding that gene expression changes linked to wound healing and stem cell activity align with hair follicle regression, which could inform strategies for hair growth and skin rejuvenation.

In this study, araliadiol, a plant-derived compound, exhibited senomorphic effects in three dermal fibroblast senescence models, suggesting its potential as a topical treatment to mitigate skin aging by reducing certain senescence-related markers and increasing procollagen type I content.

This meta-analysis reported that platelet-rich plasma significantly improved patient satisfaction and objective efficacy in treating skin aging, while not significantly increasing adverse effects.

This study reports that women with hair loss had significantly lower levels of several biomarkers, including hemoglobin, iron, copper, selenium, vitamin D, vitamin B12, folate, and thyroid hormones, compared to healthy controls.

This study demonstrates that Bazi Bushen capsules may have therapeutic potential against skin photoaging in mice by enhancing NRF2 expression and targeting the KEAP1-NRF2 pathway.

In this study, synthesized composite nanocarriers containing ribose and peptides demonstrated enhanced transdermal delivery, improved uptake by skin cells, promoted cell proliferation, enhanced antioxidant enzyme activities, and increased autophagy, suggesting a potential for more effective skin anti-aging treatments.

In this study, a systematic review highlighted the potential of exosomes in cosmetics and regenerative medicine for improving skin rejuvenation and addressing aging, while also pointing out existing challenges such as regulatory hurdles and the need for more clinical validation.

This study provides a comprehensive overview of human umbilical cord mesenchymal stem cell-derived extracellular vesicles (HUCMSC-EVs), suggesting their potential to combat aging and alleviate age-related disorders by rejuvenating multiple organs in animal models and discussing engineering strategies to harness their full anti-aging potential.

In this review, the authors discuss how hair may protect against scalp skin cancer by enabling IL-17-biased immunosurveillance, while hair loss could permit tumor development by reducing this immune protection.
