This case report reveals a diagnosis of scurvy in a 19-year-old woman, emphasizing the importance of considering vitamin C deficiency in patients with dietary restrictions presenting with specific skin and gum symptoms.

This study suggests that melatonin plays a role in hair follicle function by modulating growth and pigmentation, and it may act as a protective agent in active hair growth phases.

This review explores the complex endocrine functions of human skin and its role as a peripheral endocrine organ, but reports no new clinical results.

This review discusses recent molecular biology advances in the human phenol sulfotransferase gene family and reports no new results; the authors highlight its relevance for studies of endogenous and xenobiotic metabolism.

This review discusses the protective and stress-buffering roles of melatonin in skin functions and structures but does not present new clinical findings.

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 narrative review explores how psychological stress may contribute to premature skin aging by affecting dermal collagen and elastin remodeling through neuroendocrine, molecular, and cellular pathways, highlighting potential therapeutic targets to preserve skin structure and function.

This review discusses the brain-skin connection, the skin's role in stress response, and highlights unmet challenges in understanding stress-induced skin inflammation but reports no new experimental 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 role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

This article discusses the role of neurohormones and neuropeptides in hair follicle pigmentation and outlines promising neuroendocrinological strategies to address greying and damage, but reports no new clinical results.

This review highlights that children with adrenal disorders may experience neurological and psychiatric symptoms, with potential long-term cognitive and behavioral effects from excess glucocorticoids.

This study reports that melanocytes form a defined photoresponsive network in the skin that reads environmental light cycles and may influence the sleep-waking cycle similar to the pineal gland.

This study found that minoxidil effectively manages various types of severe hypertension but can cause side effects such as sodium retention and tachycardia.

This narrative review explores how exercise might help maintain skin homeostasis disrupted by protein deficiency, potentially by promoting processes like increased collagen synthesis and stimulating anti-inflammatory effects, though the exact mechanisms are not entirely understood.

This review explores the role of hyperandrogenism, including adrenal-derived 11-oxygenated androgen, in the development of polycystic ovarian syndrome and discusses potential therapeutic strategies targeting androgen excess, without reporting new clinical results.

This article reviews the mechanisms by which minoxidil stimulates hair growth and reports no new clinical findings.

This review examines rodent models to explore how maternal conditions like undernutrition, obesity, hypoxia, and androgen exposure affect fetal programming and metabolic outcomes in offspring, but presents no new clinical findings.

This review highlights the significant risks posed by mercury to the endocrine system, including disruptions in hormone synthesis and regulation, stress response, and potential reproductive dysfunction, while noting the need for further research on dose-response relationships and long-term impacts.

In this study, researchers identified that keloid fibroblasts respond to neurotransmitters from catecholaminergic nerves by producing bone matrix proteins, mediated by β1-adrenergic receptor activation, leading to fibro-osseous reprogramming; blocking this signaling in a rodent model prevented the development of keloid-like pathology.

This review discusses management strategies for sexual side effects of aromatase inhibitors in postmenopausal breast cancer patients and reports no original clinical findings.

This review explored the causes of hair graying and evaluated how plant-derived extracts and phytochemicals might alleviate it, noting that certain compounds showed potential in enhancing melanocyte function, reducing oxidative stress, and influencing stress-related pathways based on experimental evidence.

This study found that neurosteroids influence oxytocin secretion in sheep, particularly during stress and pregnancy, suggesting their role in protecting and maintaining pregnancy under harmful conditions.

This article reviews follicular melanogenesis, detailing how melanin synthesis and its regulation in hair follicles depend on a complex interplay of cellular and molecular mechanisms, but reports no new clinical findings.

In this study, researchers observed that fasting-induced molting in laying hens led to increased thyroid hormones, which may regulate feather molting by affecting hair follicle growth through specific signaling pathways, highlighting molecular changes during induced molting.

This review synthesizes evidence supporting the efficacy of PRP in dermatological conditions like wound healing and alopecia, but emphasizes the need for standardized protocols and larger randomized controlled trials.

This article reviews congenital adrenal hyperplasia, a group of rare genetic disorders affecting steroid synthesis, and highlights the need for specific therapy and ongoing monitoring, but reports no new clinical findings.

This study reports a method for efficiently synthesizing chromeno-pyrimidine-N-oxides in good to excellent yields, confirmed by X-ray analysis, through a reaction between 4-chloro-3-formylcoumarin and aromatic carboximide oximes.

This chapter reviews various types of aromatic compounds and provides references, but reports no new experimental results.

This review synthesizes current knowledge on choriogenesis, the final stage of oogenesis in insects, by exploring the role of follicle cells, regulatory mechanisms of gene expression, and the biochemical makeup of the eggshell, while also highlighting structural diversity and adaptations across insect species.
