In this observational study, among 135 Italian outpatients with alopecia areata, OCD symptoms were prevalent in 18.5%, and emotional distress was found in 20.7%, with emotional distress mediating the relationship between illness perceptions and OCD symptomatology.

This study found that platelet-rich plasma microneedles promoted hair regrowth in mice by facilitating angiogenesis and cell proliferation, showing promise for a minimally invasive hair regeneration treatment.

This study found that a new "bead-jet" printing system for mesenchymal stem cells in Matrigel beads improved skeletal muscle regeneration and skin healing in a high-density, sparse pattern.

In this study, researchers used a new method with platelet-rich plasma-loaded microcarriers to enhance dermal papilla cell activity and hair follicle regeneration, achieving significant hair and vessel growth in a mouse model compared to control groups.

This study found that a new FAW-FS algorithm improved recognition of depression in patients with androgenic alopecia, and comprehensive psychological interventions positively impacted their rehabilitation outcomes.

This study found that administering an adenovirus vector to increase Sonic hedgehog gene expression in mouse skin accelerated the transition of hair follicles into the growth phase, promoting hair growth.

This study found that the E3 ligases NEDD4 and NEDD4L regulate intestinal stem cell priming by degrading the LGR5 receptor, and their loss leads to increased Wnt activation and crypt proliferation, which in turn accelerates intestinal tumor progression in mice.

In a transgenic mouse model, this study found that overexpression of keratin 16 in skin keratinocytes led to hyperkeratosis and increased EGF receptor signaling, altering skin cell behavior and structure.

This study found that decreased allopregnanolone levels through inhibition or intrauterine growth restriction in guinea pigs were linked to altered brain development markers, suggesting a role for neurosteroids in fetal brain protection and development.

This study found that overexpressing PKCδ in transgenic mice did not reduce squamous cell carcinoma development induced by UV radiation, despite its effectiveness against TPA-promoted cancer in these mice.

This paper reports that noggin inhibits BMP-2 and BMP-4 functions by binding and blocking their interaction with the BMP receptor, impacting multiple developmental processes without presenting new research results.

This study identified dose levels of selenium that can produce toxicity, noting that doses as low as 2-3 µg Se/kg bw/day can lead to adverse effects, and a human mortality study linked 300 µg/day consumption to increased death risk.

This study found that long-lived proteins in mice, identified across various tissues, may be linked to neurodegenerative and cardiovascular diseases due to their low renewal rate and increased risk of damage.

This review highlights that extracts from *Hamamelis virginiana* (witch hazel) exhibit antimicrobial, anti-inflammatory, antioxidant, and wound-healing properties in various studies, showing promise for future therapeutic use in dermatology and cosmetology, particularly for skin treatments.

This review highlights the potential of microneedle technology in traditional Chinese medicine as a promising transdermal delivery system for skin diseases, showcasing improved efficacy and reduced side effects of TCM ingredients while discussing the challenges of its clinical application.

Chemical treatments can change the scale heights of wool and cashmere fibers, affecting their identification.

This article discusses the use of atomic force microscopy for examining human hair surfaces in dermatology, cosmetics, and forensic science, but presents no new research findings.

This study explored how men's perceived height and androgenetic alopecia affect social and personality impressions, reporting a potential "attractiveness malus" but noting limitations due to an older dataset, selective sample, and cultural homogeneity among raters.

This study explored social perceptions of men with androgenetic alopecia, finding that increased hair loss was associated with perceptions of being older, less attractive, smaller, and less masculine, but more family-oriented and socially agreeable, highlighting how hair loss influences first impressions.

This study found that increasing hair loss in men was associated with appearing older, less attractive, and less successful, but more family-oriented and likeable, highlighting the influence of hair loss on first impressions.

This manuscript discusses a large-scale cross-sectional analysis on addressing variance in responses to a set of questions by identifying underlying factors, but specific results are not reported in the abstract.

In this cross-sectional study, researchers found that those without a diabetic background had higher levels of secreted frizzled related protein-4, while family history of diabetes was strongly correlated with waist circumference, waist-to-height ratio, and insulin resistance but not significantly linked to protein-4 levels.

This study found that both genetic and environmental factors influence appearance-related aging in women, with skin wrinkling, hair graying, and sun damage significantly affecting perceived age more than chronological age.

This study found that fasting insulin levels are associated with increased cardiovascular and metabolic risk factors in women with polycystic ovary syndrome.

This study found that treating wheat with 100 µM melatonin under drought conditions significantly improved root and shoot growth, increased melatonin levels, and enhanced drought resistance, potentially clarifying the mechanisms of melatonin's protective effects in plants facing water scarcity.

This study observed that different hair types on Tianzhu white yaks have similar ultrastructures, but coarse hair fibers show distinct structural differences across body parts.

This article discusses diagnostic evaluations and management strategies for isosexual precocious puberty, emphasizing the importance of accurate identification and appropriate treatment, but it provides no new clinical findings.

This study found that varying the concentration of propylene glycol in rice water shampoo gel affects physical properties such as viscosity and foam height, without impacting organoleptic qualities or pH stability.

This study observed that female portraits from the past millennium show a trend of forward-moving hairlines over time, which may provide insights into the natural history of frontal fibrosing alopecia.

This study surveyed hairline preferences and found that the M-shaped contour was most preferred overall, with lower forehead heights favored by men and those without a history of hair transplantation.
