This study found that finasteride treatment in male rats altered steroid hormone homeostasis and caused kidney damage, suggesting potential risks for patients with renal dysfunction on androgen or antiandrogen therapy.

This study suggests that supporting cells are the origin of regenerated hair cells in the avian basilar papilla, with epidermal growth factor as a potential trigger, and indicates a possibility of hair cell regeneration in mammalian vestibular epithelia.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

In this study, lipid peroxides were found to induce apoptosis in hair follicle cells and advance the catagen phase in mice, suggesting a potential mechanism for alopecia development.

In this study, the authors concluded that COVID-19 may not cause direct long-term harm to testicular function, but temporary indirect effects could occur, suggesting a possible delay in pursuing parenthood post-recovery.

In this study, photodynamic therapy significantly reduced inflammatory acne lesions and sebum secretion, possibly by inducing apoptosis in sebaceous glands and down-regulating TLR-2 and TLR-4 expression.

This study found that apoptosis was more prevalent in hair follicles of women with female pattern hair loss, particularly in miniaturized follicles, and was associated with follicular inflammation.

In this study, short-term finasteride treatment reduced apoptotic factors caspase-7 and IGFBP-3 in prostate cancer cells but did not significantly affect androgen receptor expression compared to placebo.

This study suggests that finasteride may affect hair follicle growth by altering the expression of caspases and XIAP, potentially regulating the anagen phase of hair growth.

This study found that adipose-derived mesenchymal stem cells from type 2 diabetes mice were slightly less effective, yet had comparable therapeutic effects on wound healing compared to non-diabetic controls.

This study reports that finasteride treatment in men with androgenetic alopecia appears to restore caspase and XIAP expression in hair follicles to levels similar to those in individuals without the condition.

This study found that single high-dose irradiation in mice induced more severe acute skin injury and hair depigmentation, while fractional doses led to longer-term damage in the dermis and subcutis.

This study found that interleukin-10 deficiency in B6 mice led to inflammatory milk production due to maternal stress, causing alopecia and hepatocyte steatosis in pups.

This review summarizes late-breaking abstracts from the American Society for Laser Medicine and Surgery, 2018, and reports no new clinical findings.

This special issue contains abstracts from the ASA 40th Annual Meeting, providing an overview of various studies without reporting new primary results.

This study found that disrupted cholesterol homeostasis impairs hair regrowth in individuals with primary cicatricial alopecia by damaging hair follicle stem cells, highlighting the importance of cholesterol in maintaining stem cell function and hair follicle integrity.

This study found that Chrysanthemum zawadskii extract may promote hair growth by inducing an earlier conversion of telogen to anagen and increasing the proliferation of dermal papilla cells in mice and human hair follicle cultures.

This study found that haploinsufficiency of SPINK5 can lead to Netherton syndrome when a single null mutation combines with homozygous G1258A polymorphisms, suggesting it acts as a genuine mutation affecting LEKTI function.

Certain hairstyles can cause scalp diseases, smoking is linked to hair loss, 5% minoxidil foam is effective for hair loss treatment, and various factors influence wound healing and hair growth.

In this study, subdermal platelet-rich plasma injections significantly increased hair count and shaft caliber in individuals with androgenetic alopecia, with monthly treatments potentially offering greater benefits.

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 study found that low-level laser treatment with the HairMax Lasercomb significantly increased terminal hair density in both men and women with pattern hair loss, with no serious adverse events reported.

In this study, low-level laser therapy showed no statistically significant improvements in hair growth measures, despite some patients experiencing increases in terminal hairs and shaft diameter.

This article discusses the foundational concepts of nanotechnology and its contributions to dermatology and medicine, but does not present new research findings.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

Researchers developed a new type of memory using antiferromagnets that is stable, not disrupted by magnets, and works at room temperature.

This study observed that frontal fibrosing alopecia also occurs in men, with clinical features and areas of involvement similar to those seen in women, but often affecting sideburns and facial hair.

This study observed that scalp melanomas in older men often grow rapidly, appear without pigment, and have more aggressive features compared to other head and neck melanomas.

This review develops expert-guided recommendations for hidradenitis suppurativa management, highlighting evidence for the effectiveness of antibacterial and anti-tumor necrosis factor therapies, but reports no new clinical trial results.

This study found that the dermal papilla of the hair follicle regulates stem cell quiescence and regeneration by modulating Shh and Wnt signaling pathways, highlighting the importance of signaling cross talk in regeneration.
