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 observed that lifestyle modifications resulting in weight loss improved menstrual irregularity and hormonal balance among infertile obese women with polycystic ovary syndrome, although changes in total testosterone and estrone were not significant.

This source reviews advancements in microneedle-based cosmeceutical delivery, discussing new technologies and highlighting a burgeoning area of research involving microneedling combined with stem cell delivery for anti-aging, without finding measurable changes in skin barrier function or appearance during the study period.

This study observed early cardiac effects in young minipigs following high-dose doxorubicin chemotherapy, with a decrease in heart function and changes in cardiac MRI measurements compared to controls.

This study identified a new type II cytokeratin, named K6hf, exclusively expressed in the companion layer of the human hair follicle, distinguishing it from other keratins and suggesting a unique biochemical role.

This study found that wet cupping blood differs significantly from venous blood in metabolite profiles, implying distinct biochemical pathways may be involved.

This study identified the AtPRPL1 gene in Arabidopsis thaliana as being involved in cell elongation processes, despite unclear changes in cell wall composition from its altered expression.

This study observed that in aged mouse skin, there was an increase in IL-17-expressing T helper cells, γδ T cells, and innate lymphoid cells, and blocking IL-17 signaling reduced skin inflammation and delayed age-related changes, suggesting it as a potential target to mitigate skin aging.

This study describes "alarm reaction" histologic changes in pilosebaceous structures, including regression of hair matrix and alterations in sebaceous glands, affecting follicular and sebaceous gland morphology.

This study found that administering dutasteride did not change spermatogenesis or oxidative stress levels in rat testes, though further research is needed to confirm these findings.

In this study, significant changes in hair fiber dimensions were observed between pre- and post-operative states in males undergoing abdominal surgery, with values normalizing by the fourth post-operative week.

This abstract does not provide specific findings or results.

This study found that manipulating prolactin levels in New Zealand Wiltshire sheep induces wool follicle growth cycles, revealing gene expression changes that suggest roles for specific genes in follicle function.

This article reviews changes in men's sexual health after midlife, exploring physiologic changes, psychological factors, and various treatment options, but it presents no new clinical results.

This study concluded that dietary changes alter serum progesterone and estradiol levels in late gestation ewes, likely due to metabolism rather than changes in placental steroid synthesis.

This review suggests systemic changes in polycystic ovary syndrome may increase the risk of neurodegeneration, potentially linking it to Alzheimer's disease through common pathways affecting tryptophan metabolism.

This study analyzed changes in the microbiota during antler velvet regeneration in sika deer and found significant differences in microbial community composition between 15 and 30 days post-pedicle casting, highlighting the potential roles of specific bacteria in wound healing and tissue regeneration.

This study found that all examined biomarkers and clinical features were elevated in systemic lupus erythematosus patients, particularly ANA and Anti-dsDNA autoantibodies, but no single biomarker was sensitive or specific enough for diagnosis.

This study suggests that changes in expressed transcripts and splice isoforms may explain the transition from curly to straight fleece in Chinese Tan sheep as they age.

Retinoic acids temporarily change skin stem cells to a slower cycle and more differentiated state.

This study found that prostate cancer aggressiveness in men with obesity is associated with changes in age, BMI, testosterone, and estradiol levels, and that adipocyte-secreted molecules increase cancer cell aggressiveness in vitro.

This study suggests that breast cancer-associated phospholipids may alter the X-ray diffraction pattern of hair, potentially enabling the development of a sensitive and specific screening test for breast cancer.

In this study, the expression of certain hair follicle-related genes differed between growth phases in Angora goats, with HOXC13 showing overexpression during the anagen phase, potentially influencing the mohair's shine and texture.

This review investigates the potential benefits of cinnamon supplementation alongside lifestyle changes for managing obesity and polycystic ovary syndrome, but it reports no new clinical results.

This review discusses the evaluation of skin conditions during pregnancy and emphasizes the importance of testing for syphilis, but it reports no new clinical 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 review discusses how the hormonal changes of menopause affect skin and hair, highlighting improvements in skin symptoms like dryness and reduced wound healing with estrogen supplementation, and advises healthcare providers to consider broader potential benefits of menopausal hormone therapy when consulting patients.

This study found that HOXC13 gene expression was significantly higher during the anagen phase in Angora goats, potentially contributing to the mohair's shiny and silky nature.

This study found that clinical and biochemical markers of hyperandrogenism were more common in post-adolescent and early adult-onset acne among women than in adolescent acne.

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.
