This study found that minoxidil increased plasma renin activity in patients with hypertension through both an adrenergic mechanism related to heart rate changes and a secondary mechanism unrelated to propranolol.

This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

Stress can cause hair to turn gray by depleting stem cells.

Treating sleep apnea in young obese women with PCOS can improve heart health and insulin sensitivity.

This study found that patients with polycystic ovary syndrome have reduced heart rate recovery, an exaggerated systolic blood pressure response to exercise, and decreased heart rate variability, implying possible autonomic dysfunction.

This article discusses the potential of acupuncture as a complementary or alternative therapy for PCOS, highlighting experimental evidence of its positive effects on reproductive and metabolic function, but reports no new clinical results.

This study observed that middle-aged women with Polycystic Ovary Syndrome who practiced yoga Nidra for twelve weeks experienced improvements in stress, anxiety, and depression compared to a control group that did not participate in any intervention.

This study found an imbalance in autonomic nervous system activity in patients with androgenetic alopecia, with increased sympathetic activity and decreased parasympathetic activity compared to a control group.

This study reported that stress can induce hair graying in mice through noradrenaline-mediated depletion of melanocyte stem cells in hair follicles, providing a mechanism that connects stress to hair color changes.

This article presents a case of central serous chorioretinopathy occurring after the use of topical minoxidil solution, but reports no clinical study findings.

This study found that acute stress can cause rapid hair loss by triggering necrosis in hair follicle cells and initiating autoimmunity, revealing a mechanism where stress-induced nerve activity leads to tissue damage and immune system activation.

This study found that individuals with androgenetic alopecia exhibited an imbalance in autonomic nervous system activity, characterized by increased sympathetic activity and decreased parasympathetic activity compared to controls.

This study found that sympathetic nerves and arrector pili muscles form a niche that modulates hair follicle stem cell activity, revealing their role in hair follicle regeneration.

This review discusses recent advancements in understanding how the sympathetic nervous system and norepinephrine regulate hair follicle growth, highlighting innovative studies that explore their effects on hair follicle stem cells.

This study found that arrector pili muscles formed by Sonic Hedgehog signaling play a critical role in maintaining sympathetic nerve connections to hair follicle stem cells, influencing hair regeneration, with implications for hair loss treatments.

This study found that stress-induced signaling from the sympathetic nervous system in mice led to the depletion of stem cells in hair follicles, resulting in premature greying.

This article reviews the underlying mechanisms of segmental vitiligo with white hair, focusing on skin and hair follicle melanocytes, and proposes potential targets for treatment, highlighting neuroendocrine factors as possible contributors to the condition.

This study explored the complex roles of niche cells in regulating hair follicle stem cells, identifying specific cell functions such as signaling, sensing, and relaying messages, which could provide insights into treating hair loss conditions like androgenetic alopecia and alopecia areata.

In this study on mice, intensive stress through methods like resiniferatoxin injections and physical restraint was found to inhibit hair follicle growth, with the mechanism involving the sympathetic nervous system and the cAMP signaling pathway in hair follicle stem cells.

This study observed that, in rats, modeling sinus lifting and septoplasty led to increased sympathetic nervous system activity and metabolic shifts in the early postoperative period due to inflammation.

In this study, chronic finasteride administration in near-term pregnant rats restored baroreflex control of renal sympathetic nerve activity to levels observed in non-pregnant rats.

In this study, the authors identified a role for hair follicles in regulating the formation and sympathetic innervation of arrector pili muscles, influencing hair follicle stem cell activity and potentially explaining hair loss associated with beta-blockers and androgenic alopecia.

The study found that experimental inflammation from nasal septum surgery in rats caused a shifts in autonomic nervous system balance, with sympathetic dominance and parasympathetic suppression, normalizing after one week.

This study found that septoplasty simulation in rats led to decreased exploratory behavior and anxiety, suggesting a link between postoperative stress and changes in the hippocampal region.

This review discusses the association between polycystic ovarian syndrome and hypertension, highlighting evidence of metabolic factors influencing this potential link and stressing the need for further research in this area.

This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.

This study found that human chymase overexpression in transgenic mice may contribute to increased mortality from LPS treatment compared to wild-type mice.

This review highlights that disturbances in neuroimmune communication, particularly between sympathetic nerves and macrophages, may contribute to autoimmune diseases like rheumatoid arthritis and type 1 diabetes, and suggests potential therapeutic avenues by restoring this communication in preclinical and early clinical studies.

This review highlights that while moderate physical activity benefits skin health by improving circulation and reducing stress, intense exercise or inadequate protective measures can harm the skin, emphasizing the need for sun protection and personalized care.

Propranolol affects heart rate and renin levels in minoxidil-treated patients.
