This study found that melatonin receptor genes play a key regulatory role in the development of goose skin feather follicles during embryonic development.

In this study, Malassezia pachydermatis infection was more common in German shepherd dogs and occurred more frequently in January and February compared to other months in Diyala Governorate.

A new hair transplant method showed promising results and a study found how deep a CO₂ laser can penetrate skin.

Minoxidil reacts to nitrosation 7 times more than phenol, mainly due to its -NH₂ groups, leading to the creation of N-nitrosominoxidil.

This review discusses definitions of polycystic ovary syndrome and reports no new clinical results; the authors support using modified 1990 NIH criteria and acknowledge ongoing evolution as research advances.

This review discusses the definition of polycystic ovary syndrome proposed by the AE-PCOS Society Task Force, emphasizing hyperandrogenism, ovarian dysfunction, and excluding related disorders, while noting potential variations needing more research.

This paper reviews the diagnostic criteria, associated morbidities, and possible evolutionary advantages of polycystic ovary syndrome, but does not report any new findings.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This review discusses the various evidence-based and potential applications of metformin in treating and preventing symptoms and complications associated with polycystic ovary syndrome but reports no new clinical results.

This study identified three novel genetic loci associated with PCOS and found similar genetic architecture across different diagnostic criteria, with evidence suggesting genetic links between PCOS and various metabolic and psychological traits.

Lichen Planus is a less common condition affecting skin and mucous membranes, with various types and associated risk factors, challenging to diagnose, significantly impacts life quality, and may have a risk of cancerous changes in oral lesions.

This review discusses the complex etiology of polycystic ovary syndrome (PCOS), highlighting its association with insulin resistance and hyperandrogenism, but reports no clinical findings; the authors suggest further investigation of the pathophysiological mechanisms.

This article discusses the hair follicle's regenerative cycles and the molecular mechanisms influencing them, emphasizing the need for therapeutic targeting of the "hair cycle clock" to manage hair growth disorders, without reporting new research findings.

This article discusses the potential role of melatonin in protecting skin against stress and maintaining homeostasis, based on its local synthesis and various protective functions, but presents no new clinical results.

This review discusses the various treatment options for male and female pattern hair loss and provides no new clinical results; the authors outline the most effective strategies based on existing evidence.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This review discusses the diagnosis and treatment of hirsutism, emphasizing that a systematic evaluation can determine its cause, while combination therapy effectively manages the condition for most patients.

This study found that the prevalence of androgenetic alopecia increases with age among both men and women in Maryborough, Australia, with 57% of women and 73.5% of men aged 80 and over affected.

This review discusses side effects and allergy contact dermatitis caused by essential oils in cosmetic products and reports no new clinical results.

This review discusses the role of oestrogens in stimulating growth hormone secretion and influencing linear bone growth in children, and reports no new clinical results; the authors suggest that oestrogens play a key role in pubertal growth spurts for both genders.

This article discusses the cutaneous side effects of various chemotherapeutic agents but reports no new clinical results; the authors emphasize the importance of dermatologists recognizing drug-induced skin reactions to better patient care.

This article discusses the influence of estrogens on hair follicle growth and metabolism, suggesting a significant role alongside androgens in hair growth control but reports no new clinical results.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

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.

This study found that transcriptome profiling of cashmere goat skin revealed key genes and pathways involved in hair follicle initiation, differentiation, and maturation, which are critical for improving fleece production.

This review examines regenerative hair waves and complex hair cycle domains in transgenic mice, highlighting how these dynamic processes contribute to skin regeneration and the physiological regulation of organs, but reports no new experimental results.

This study found that hair follicles in both mice and humans may serve as an important site for melatonin synthesis and signaling, potentially influencing hair cycle regulation by modulating keratinocyte apoptosis.

This article explores the dynamic and energy-efficient nature of telogen hair follicles, challenging the notion of dormancy, and highlights their potential in advancing treatments for hair growth disorders.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This study discovered that the circadian clock influences hair follicle regeneration, making hair grow faster in the morning and causing more radiation-induced hair loss in the morning compared to the evening.
