This publication discusses the 2021 ESC Guidelines for the prevention of cardiovascular disease in clinical practice and reports no new results.

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 male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

This review provides a comprehensive overview of melatonin's physiological roles, effects, and clinical implications, but it does not present new experimental findings.

This article suggests that modern lifestyle changes, including diet, stress, and chronic anti-inflammatory medication use, may disrupt the natural process of inflammation resolution, increasing vulnerability to chronic disease.

This chapter reviews the role of self in disorders related to the OCD spectrum, such as hoarding disorder, body dysmorphic disorder, and trichotillomania, and reports no new findings.

This joint position paper by several Polish medical societies examines guidelines and recommendations for managing conditions like obesity, hypertension, and liver disease, underscoring the importance of a collaborative, interdisciplinary approach in treatment. Results are not explicitly reported.

This review reports that hair follicles are dynamic neuro-immuno-endocrine organs with intrinsic signaling pathways, which play a crucial role in hair disorders like alopecia. It highlights emerging regenerative approaches targeting these pathways for hair restoration.

This study explored the experiences of adolescents with alopecia and their parents, highlighting the emotional distress caused by the condition and the inadequate response of healthcare professionals to their needs.

This article reviews the role of stem cells in tissue development, tumor formation, and organoid generation, and highlights the potential of epigenetic regulation in advancing regenerative medicine and cancer treatment, without presenting new experimental results.

This review discusses the relationship between insulin regulation and hyperandrogenemia in polycystic ovary syndrome, suggesting potential benefits of insulin-lowering treatments for ovarian function but reporting no definitive results for hair-related symptoms.

This article reviews the endocrine changes in anorexia nervosa and bulimia nervosa, highlighting hypoleptinemia as a potential mediator, but does not present any new clinical results.

In this study, researchers examined androgen receptor activity in the adult mouse brain and found specific expression in key brain areas, which could inform understanding of cognitive side effects in humans undergoing androgen deprivation therapy for prostate cancer.

In this thesis, researchers explored ways to enhance the management of myotonic dystrophy type 1 by investigating the genetic inheritance patterns, especially small-sized repeat expansions, and assessing cardiac care, energy expenditure, and body composition in affected individuals.

This review highlights the role of the skin's photosensory system in mediating responses to UVA radiation, contributing both to immediate protective effects and to broader circadian and seasonal adaptations, but reports no new experimental results.

This review discusses recent advancements in hair follicle regeneration technologies, including the authors' own development of functional hair regeneration through bioengineered follicle germ transplantation, but reports no new clinical results.

This review discusses the molecular mechanisms driving hair follicle degeneration in skin aging and emphasizes the role of the tissue microenvironment on stem cell function, but reports no new research findings.

This study found that hair follicles across mouse skin form a heterogeneous regenerative field, with distinct cycling dynamics influenced by the balance of activator and inhibitor signals, which could inform other organ regeneration research.

This review highlights capsaicin's chemical properties, natural sources, and its potential benefits such as antioxidant, anti-inflammatory, and analgesic effects, while also noting its challenges in food applications regarding dosage, taste perception, and regulatory compliance.

This study observed that developing mammary organs in Monodelphis domestica show mammary hairs in 12-week-old females, which disappear by 18 weeks, with findings suggesting shared characteristics between their nipples and eutherian nipples, supporting the evolutionary link between mammary glands and hair organs.

This study found that hair follicles in mouse skin use common activator/inhibitor signals to maintain cyclical hair growth across different regions, with varying dynamics influenced by distinct anatomical domains.

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

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.

This study found that treating neonatal mice with the neurotoxin 6-OHDA resulted in temporary hair loss and thinner skin compared to control mice, linking sympathetic neurons to hair growth and skin thickness.

This report describes two cases of VKH disease and SO where severe alopecia, likely due to incomplete treatment, improved following systemic steroid therapy.

This study found that concentrated clusters of noradrenergic nerve fibers form a longitudinal linear system in rat skin, particularly innervating arrector pili muscles.

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 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 study on C57BL/6 mice found that subcutaneous cholesterol injections significantly promoted hair regeneration by enhancing hair follicle stem cell proliferation, highlighting the role of the PKA-tyrosine hydroxylase-sympathetic nervous system pathway in this process.

In this study, rat vibrissa follicles transplanted into mice demonstrated survival, partial sympathetic nerve reinnervation, and increased norepinephrine levels 37 days post-implantation, suggesting potential for hair growth despite not returning to normal nerve function.
