This study suggests that human evolution involved accelerated changes in the HR gene, affecting its role in mediating postnatal hair cycling.

This study found that the transcriptome of skin stem cells in mice changes significantly with age, revealing specific age-dependent biological programs and transcriptional hubs.

This review discusses the role of histone deacetylases in hearing loss, proposing potential pharmacological interventions, but reports no new clinical results.

This study found that certain dietary changes, such as a low glycemic load diet for men and specific supplements for women, may improve acne, while chocolate, whey proteins, and dairy products are linked to worsened symptoms in both genders.

Certain proteins involved in DNA modification may affect the genetic changes in systemic lupus erythematosus and could indicate the disease's activity.

This study found that finasteride treatment of male rats led to changes in their male offspring's testicular gene expression, potentially affecting sperm function in response to odorant-like signals.

This study found that a newly identified mutation in the hairless gene in mice led to decreased Hr mRNA levels and changes in gene expression related to hair follicle development.

This study investigated the Mandarin duck as a model for understanding lifelong developmental changes, finding that male sail feather morphogenesis involves a combination of local morphogenetic programs, epigenetic regulation, and hormonal cues, with increased female estrogen levels observed before the mating season.

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 review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

This study reports that chemically induced short anogenital distance in male rat fetuses involved distinctive transcriptional changes, suggesting roles for estrogen and Wnt2 signaling in anogenital tissue development.

This study explored peripheral blood immune dysregulation in alopecia areata through single-cell analyses, identifying systemic changes linked to disease severity and key signaling roles for monocytes, NK cells, and memory T cells, suggesting potential therapeutic targets.

In this study, D-OCT imaging revealed distinct structural and vascular changes in patients with frontal fibrosing alopecia, highlighting the technique's potential for diagnosing and monitoring the condition's activity.

This article reviews treatment strategies for ovulation induction in women with PCOS seeking pregnancy, emphasizing lifestyle changes and pharmacological options, and reports no new clinical findings.

In this study, researchers overexpressed Lrig3 in mouse skin and observed hair loss linked to changes in skin protein profiles and signaling pathways, suggesting a potential role for Lrig3 in maintaining skin homeostasis.

This study found that H-Ras activation in aged mouse skin leads to increased dysplasia and progression to in situ squamous cell carcinoma, highlighting an age-linked connection between immune changes, senescence, and cancer risk.

This review discusses the International Evidence-Based PCOS Guidelines, which aim to improve diagnosis and management of PCOS and its associated comorbidities, noting the importance of early intervention and healthy lifestyle changes; it reports no new results.

This study found that serum vaspin levels were elevated in women with polycystic ovary syndrome compared to controls, but treatment with metformin or weight loss did not significantly change these levels.

This study observed dynamic behaviors such as cluster formation, migration, and active proliferation of transplanted bone marrow cells in a mouse model, providing insight into cellular-level changes post-transplantation.

In this study, researchers found that two dominant haplotypes in the EDA2R/AR intergenic region have likely been shaped by demographic changes and selection during human evolution, particularly notable in African and non-African populations.

This study found that depleting fibroblasts in the skin does not affect the proliferative capacity of epidermal stem cells at various ages, suggesting robust compensatory mechanisms maintain skin functionality despite these cellular changes.

This study found that COVID-19 infection disrupts spermatogenesis, alters testicular cell populations, and may impact male fertility by causing long-term changes in testicular function and reduced sperm quality, as observed even in patients who have recovered from the acute phase of the infection.

This review explores how radiation-induced hair graying can be used as a model to study the mechanisms behind hair graying, focusing on cellular senescence and potential therapeutic targets to address age-related changes. Results are not provided.

This study found that a catalytically active version of Vav2 significantly altered gene expression patterns in hair follicle stem cells in mice, with these changes varying over the animals' lifespans.

Genetic changes in mice help understand skin and hair disorders, aiding treatment development for acne and hair loss.

This review explores the role of aging-related changes in skin, discussing how impaired skin barrier function may contribute to systemic inflammation, or "inflamm-aging," which in turn could impact the broader decline in organ and tissue function seen in aged individuals.

This review discusses the relationship between aging, chronic inflammation, and immunosuppression, suggesting that these interconnected processes may contribute to tumorigenesis and premature aging, but reports no new experimental results.

This review synthesizes both traditional and emerging molecular mechanisms of tissue remodeling across different organs, aiming to establish a theoretical basis for precision interventions in pathological conditions, according to the authors.

This study found that bioelectric and biochemical signaling mechanisms coordinate collective cell movement during chicken feather bud morphogenesis, suggesting a potential new angle for research in skin development and wound healing.

This study found that 6 months of Low-Level-Laser Therapy significantly increased overall hair density, particularly Vellus hair density, in women with hormonal, age-related hair loss.
