This article provides contact information for Bruce A. Morgan and features no new research findings.

This study found that hair products used by Black women and children in the U.S. contain multiple chemicals associated with endocrine disruption and asthma, highlighting potential exposure disparities and a need for improved labeling.

This study reports that three synthesized PSMA-targeted radioimaging agents demonstrated high affinity and specific localization to prostate cancer tumors in a mouse model, highlighting their potential for cancer detection and monitoring.

This review discusses the potential benefits and risks of 5α-reductase inhibitors in preventing prostate cancer and reports no new results.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

This study in Japan found varying prevalence of skin disorders, with atopic dermatitis common in children and tinea pedis in the elderly, and observed gender differences in disease susceptibility.

This study found that balding dermal papilla cells show premature senescence and altered expression of stress and DNA damage markers, suggesting sensitivity to environmental stress in androgenetic alopecia.

This review discusses the mechanisms associated with protoporphyrin IX in living cells and reports no clinical results; the authors emphasize its potential in cancer diagnosis and the risks of toxicity.

In this study, researchers found that transgenic expression of the Hairless gene in keratinocytes can restore hair follicle regeneration in Hr-deficient mice by repressing Wise, a modulator of Wnt signaling.

This study observed that autologous platelet-rich plasma treatment improved hair count and density in areas with androgenetic alopecia compared to placebo, with differing outcomes based on the PRP collection device used.

This study found that overexpression of PKCα in mouse epidermis increases expression of specific proinflammatory mediators and induces inflammation but does not significantly affect epidermal differentiation, proliferation, or tumor promotion with TPA.

This study found that a truncated region of the K5 promoter directs expression in stratified epithelia, particularly in epidermis, hair follicles, and tongue, potentially involving specific keratinocyte nuclear proteins in regulation.

This study found that differentiated cells of the corneal epithelium can be converted to hair and interfollicular epidermis through a multistep process involving dermal developmental signals.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

In this study, researchers found that extrafollicular progenitors marked by Hic1 are the main contributors to reparative fibroblasts in wound repair, with potential to modulate healing outcomes through genetic and pharmacological interventions.

This study found that feeding aged mice a probiotic yogurt induced changes leading to thicker, healthier fur, suggesting a bacteria-triggered interleukin-10-dependent mechanism that mimics signs of youth and reproductive fitness.

This randomized pilot study suggests that finasteride may benefit some men with category IIIA chronic pelvic pain syndrome, although it is not recommended as monotherapy unless benign prostatic hyperplasia is also present.

This review discusses best practices for minimizing complications with dermal fillers and provides guidance based on expert consensus, yet it reports no new clinical results.

This study found that the prevalence of androgenetic alopecia in Chinese men and women was lower than in Caucasians and similar to that in Koreans.

Specific cross-linkages help make hair proteins stable and strong.

This review discusses different processing methods for isolating human AD-SVFs/AD-MSCs using various kits and reports no new clinical results, highlighting the need for standardized preparation techniques.

Finasteride effectively inhibits 5α reductase, while plant extracts like Permixon and Bazoton don't show significant results.

This study reports that progesterone metabolism to DHP and THP is necessary for its neuroprotective effect against kainic acid excitotoxicity in ovariectomized rats, unlike the synthetic progestin MPA.

This study found that keratin and other hair proteins in humans are extensively modified posttranslationally, which helps explain the structural characteristics of mature hair.

This review discusses evidence on androgen sensitivity as a potential factor in COVID-19 disease severity, suggesting that androgen receptor interactions could influence virus entry and progression, and reports no new clinical results.

In this study, the prevalence of polycystic ovary syndrome in southern China was found to be 2.2%, with affected women showing distinct metabolic and hormonal characteristics compared to others.

This study reports the discovery of mutations in the PADI3, TGM3, and TCHH genes as molecular genetic causes of uncombable hair syndrome in children, indicating an autosomal-recessive inheritance pattern.

This study found that the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This study found that approximately 75% of women with PCOS exhibited hyperandrogenemia, with free testosterone being the most frequently elevated marker.
