This study found that inhibiting autophagy in mouse preputial glands alters lipid metabolism, delays aging-related duct changes, and reduces pheromone production, indicating autophagy's critical role in gland homeostasis and cell breakdown during secretion.

This study found that autophagy in the preputial glands of mice plays a crucial role in regulating lipid and fatty acid metabolism, as well as pheromone production.

This study found that treating aged mice with the Cdc42 inhibitor CASIN restored hair follicle stem cell functionality and improved hair regeneration by inducing anagen onset and increasing anagen skin areas.

RCS-01 is safe and may help rejuvenate aging skin.

The document recommends personalized, culturally sensitive treatments to rejuvenate the aging Asian face, focusing on natural results and specific techniques for skin, hair, and facial features.

This study suggests that selenium deficiency accelerates aging-related health deterioration in mice with short telomeres, providing a model for exploring selenium’s role in human aging.

This case report describes a patient's psychiatric and medical journey after a cardiac arrest, focusing on managing agitated behavior without medication, leading to significant improvement in cognitive function over a 5-week hospital stay.

This review discusses the phytochemistry and pharmacological properties of Martynia annua but reports no new findings; it suggests the plant's various phytoconstituents offer scope for future research.

This article discusses the role of estrogens in skin aging and reports no new findings; it highlights the potential of selective ER modulators to improve skin health without systemic side effects.

This study observed that Japanese women experience diffuse central hair loss after age 40, characterized by reduced hair density and thicker hair ratio rather than vellus-like hairs.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This study suggests that short telomeres may produce similar aging-related symptoms across different segmental progeroid syndromes, offering potential insights into normative aging processes.

This review explores how estrogens influence skin health and attractiveness in women, particularly with aging, but it reports no new clinical findings.

This study suggests that the susceptibility of hair follicle melanocytes to oxidative stress as they age may be key in the graying of hair due to reduced catalase expression and activity.

This study observed that hair regrowth in mice was irregular and delayed more in older mice, with increased enzyme activities in hair re-growing areas compared to non-growing areas.

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 review discusses the impact of melatonin and its metabolites on skin aging, summarizing how they may serve as "aging neutralizers" through their anti-oxidative and anti-inflammatory properties, but reports no new clinical results.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This study found that hair luster decreases with age in Japanese females, primarily due to an irregular increase in fiber curvature which affects hair alignment.

This study found that the DPP-4 inhibitor linagliptin slowed the progression of premature aging characteristics in klotho-/- mice, including improved body weight, cognitive function, and hair retention.

In this study, lifelong barley intake in SAMP8 mice was associated with extended lifespan, improved aging-related phenotypes, and beneficial shifts in the intestinal microbiome.

In this study, researchers characterized the normal scalp hair properties in South Koreans, observing that hair density declined with age and varied across scalp sites, while hair thickness patterns remained relatively stable until later in life.

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.

In a study using hairless mice, tranexamic acid was found to ameliorate natural skin aging, with stronger effects observed in female mice compared to males.

This review summarizes how common polymorphisms in androgen and estrogen receptor genes may influence aging-related symptoms and diseases in men, but it reports no new clinical results.

This review discusses the role of tissue mechanics and extracellular matrix in skin aging processes and highlights potential therapeutic strategies, but reports no new clinical results.

This review discusses the potential of platelet-rich plasma in regenerative medicine and aging-related diseases but notes that clinical efficacy remains unclear due to varying study results and preparation inconsistencies.

This study found that restoring hypothalamic NPY levels in mice delayed aging-related characteristics such as fat loss, hair loss, and memory decline, suggesting that maintaining these levels could be important for counteracting aging and its effects.

In this study, researchers reviewed the literature on the preventive and therapeutic roles of exercise in various skin diseases and assessed whether there are sufficient data to recommend exercise for each condition.

This review discusses recent advancements in skin epigenetics, focusing on how epigenetic mechanisms regulate gene expression during normal skin function and their dysregulation in conditions like skin disorders and cancer, but reports no new clinical results.
