This book discusses current research on polycystic ovary syndrome, including diagnosis, management, and the impact of lifestyle changes, without reporting new clinical results.

This study identified non-structural proteins in preschool children's scalp hair that suggest potential biomarkers for brain development, immune function, and stress response with heritability and age-related differences.

This review discusses cross-sex hormone therapy for managing gender dysphoria in transsexual individuals and reports no new clinical results; it highlights the need for education and culturally sensitive training for healthcare professionals.

The document concludes that individualized treatment and lifestyle changes are important for managing menopause symptoms and health risks.

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 observed that mink dermal collagen fibrils undergo structural changes during the hair cycle, with increased fiber thickness and bundle density as minks grow.

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.

Managing metabolic syndrome needs both lifestyle changes and medical treatments.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

In this study, researchers using a multi-omics approach identified specific proteins involved in the hair follicle cycle of Inner Mongolia Cashmere Goats, finding that API5 affects apoptosis, while ribosomal proteins are highly expressed during the resting stage, providing insights into hair follicle growth and apoptosis.

This article reviews both minimally invasive and surgical procedures used to treat periorbital aging, highlighting advancements in rejuvenation techniques for areas like the eyebrows and eyelids.

This review examined mechanisms regulating muscle repair, highlighting disruptions in aging and chronic diseases like Duchenne muscular dystrophy and diabetes. It noted that chronic inflammation and metabolic dysfunction hinder effective regeneration and discussed emerging therapies, suggesting multi-target approaches could be promising despite limited clinical evidence.

This study found that finasteride treatment in male rats may lead to changes in connexin 43 expression in the testes of their offspring, potentially affecting spermatogenesis.

This article discusses the increasing use of lifestyle drugs by healthy individuals to alter appearance or slow aging and emphasizes the need for doctors to consider side effects and contraindications, but it reports no new clinical findings.

This study found that septoplasty simulation in rats led to decreased exploratory behavior and anxiety, suggesting a link between postoperative stress and changes in the hippocampal region.

This review explores the mechanisms of hair cell death due to factors like noise, ototoxic drugs, and aging and reports no conclusive clinical results; ongoing research may eventually enable preventive treatments for hearing loss.

In this study, researchers observed that the combination of hair progenitors and their micro-niche changes every three days in mouse zigzag hair, and disruptions in specific genes affected this rhythm, highlighting the importance of this periodic change for normal hair morphology.

This study observed that among elderly patients, the most common systemic disease associated with skin conditions was diabetes, while wrinkling and xerosis were prevalent skin changes.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This study on rats found that finasteride and dutasteride increased collagen density in penile tissues and caused changes in prostate cells, but did not significantly alter erectile pressures compared to controls.

This study highlights that modern facial rejuvenation techniques have shifted toward minimally invasive injectable methods, with botulinum toxin and hyaluronic acid fillers effectively reducing wrinkles, enhancing facial features, and temporarily addressing age-related facial changes as alternatives to more invasive surgery.

This study found that photobiomodulation after septoplasty reduced pain and inflammatory response, leading to less pronounced changes in autonomic nervous system activity compared to patients who did not receive this treatment.

This study found that cetaceans have adapted their fibroblast growth factors to assist in low bone density, hypoxia tolerance, and the development of rigid flippers, reflecting significant evolutionary changes for aquatic life.

This review highlights men's cosmetic interests, focusing on maintaining a masculine appearance while managing scalp hair, facial lines, and other aging signs, but presents no new findings.

In this study, RT1640 was found to promote hair pigment system regeneration and expand melanocyte stem cell pools in a mouse model, suggesting potential applications for aging-related hair disorders.

This review highlights that exosomes from adipose-derived stem cells, particularly those enriched with circ-Ash1l, can inhibit ferroptosis and reduce UVB-induced skin aging by delivering GPX4-promoting signals to damaged cells, thus offering a potential regenerative therapy for photoaged skin.

This study found that subchronic finasteride treatment in male rats altered neuroactive steroid levels and steroid receptor expression in the brain, with some changes persisting after drug withdrawal.

This study found that self-noncoding dsRNA activates TLR3 to stimulate intrinsic retinoic acid synthesis, promoting new hair follicle formation in wounded mice and showing similar gene expression changes in humans treated with rejuvenation lasers.

This study evaluated the quality of life and mental health of patients after moderate traumatic brain injury, reporting changes in physical, mental, and social health as measured by various health scales.

This review highlights new perspectives in genomics and epigenomics for skin rejuvenation, comparing innovative strategies like senolytics and DNA repair modulators with classical treatments, and emphasizing the importance of tailoring therapies using individual genomic profiles for personalized anti-ageing approaches.
