This review discusses the roles of peripheral nerves in stem cell and immune responses within the skin and hematopoietic system, emphasizing their potential in developing new therapies; it reports no new experimental results.

This review highlights advances in understanding trichotillomania's neurobiology and treatment, noting behavior therapy's effectiveness and new pharmacological and digital therapies, while addressing underdiagnosis, stigma, and research gaps.

This review discusses the neurobiology of sexual function and reports no new results; the authors cover multiple endocrine and neurotransmitter influences on sexual desire, arousal, and orgasm stages.

This review discusses the psychological and neurobiological aspects of trichotillomania and reports no new results, emphasizing the need for further research on its treatment and neural mechanisms.

In this review, researchers analyzed literature on trichotillomania and found advances in understanding its neurobiology—highlighting dysregulated reward circuits and genetics—and treatments, with behavioral therapy and innovative pharmacological approaches improving outcomes where traditional SSRIs do not.

In this literature review, researchers highlighted that trichotillomania involves dysregulated reward circuits, abnormal sensory processing, and potential genetic factors, advancing both therapeutic strategies and understanding of the condition, but stigma and provider training gaps persist in effective care provision.

This study found that high doses of progesterone significantly inhibited neuroblastoma growth in both in vitro and mouse models, while showing selective toxicity and minimal harm to healthy cells.

This study found that using SH-SY5Y cell lysate in Western blot analysis may improve the diagnosis of Satoyoshi syndrome by providing more consistent and clear immunoreactive band patterns compared to brain homogenate, potentially leading to earlier diagnosis and treatment.

This study identified a small molecule that activates GLI1, suppressing neuroblastoma cell growth, which may aid in developing new treatments for high-risk neuroblastoma cases.

In this study, tea tree oil was found to have substantial antibacterial activity and promote proliferation and migration of hair follicle stem cells in vitro, indicating potential benefits for treating scalp alopecia areata.

This study found that dauricine, a natural compound, may inhibit cell growth and enhance apoptosis in neuroblastoma and glioblastoma by blocking the Oct4/Shh pathway and AKT/β-catenin signaling.

This article reviews the clinical applications of botulinum toxin, highlighting its effectiveness in treating various pain conditions like diabetic neuropathy and chronic migraines and noting future research should focus on enhancing safety and efficacy.

This research observed that 5α-reductase inhibitors showed significant tic-suppressing effects in Tourette's syndrome, suggesting a key role for this enzyme in the disorder's pathogenesis.

This study suggests a potential link between hair dye exposure during periconception or pregnancy and certain adverse obstetric and pediatric outcomes, but the evidence remains preliminary and uncertain.

In this literature review, it was reported that mental health disorders may both contribute to and be exacerbated by various types of hair loss, and an interdisciplinary treatment model is recommended for effective diagnosis and patient care.

This study explores the neurobiology and genetics of barbering (hair and whisker biting) in laboratory rodents, and its potential links to stress, aggression, grooming, and stereotypic behaviors, highlighting its significance in experimental work with these animals.

Finasteride's sexual side effects not caused by androgen deficiency or SRD5A inhibition.

This review discusses the neurobiology and proposed mechanisms of scalp itch, but it does not report new clinical findings, highlighting the need for further research in this area.

This study reports that in human glioblastoma and neuroblastoma cell lines, 24-hydroxycholesterol significantly suppressed the conversion of testosterone to growth-inducing androgens via the 5α-reductase pathway, revealing a new connection between cholesterol homeostasis and androgen metabolism.

This review summarizes proposed pathophysiological mechanisms of postpartum depression, highlighting neuroendocrine and neurobiological changes, but reports no new findings and calls for integrated understanding of the disorder.

In this study, researchers explored how hypoxic preconditioning affects the survival and oxidative stress resilience of nestin-expressing hair follicle stem cells and SH-SY5Y neuroblastoma cells, focusing on changes in gene expression for HIF1α, BDNF, and VEGF.

This study found that Botox® was most effective at a 25 U/ml concentration, while Dysport® and Neurobloc® were optimal at 100 U/ml for producing anhidrotic areas after injections.

This study found that certain gene sets, including those involved in ligand-gated ion channel signaling and cell adhesion, are associated with Tourette syndrome, suggesting a potential neurobiological basis for the disorder.

This review discusses OCD spectrum disorders with dermatological symptoms, emphasizing their clinical features, neurobiology, and treatment options, while noting the need for more controlled studies.

This study identified gene sets associated with Tourette Syndrome, implicating Ligand-gated Ion Channel Signaling, Lymphocytic, and Cell Adhesion and Trans-synaptic Signaling processes in the disorder's neurobiology.

In this study, cepharanthine showed potent antiviral effects against tick-borne encephalitis virus in vitro by reducing viral replication and inflammation in human lung and neuroblastoma cells.

This review concludes that anabolic–androgenic steroid abuse may lead to significant neurotoxicity, affecting brain structure, neurotransmitter systems, and increasing the risk of mood disorders and cognitive deficits.

Understanding genes and hormones is crucial for managing male puberty and sex development disorders.

In this study, patients with seasonal affective disorder were found to have increased functional connectivity in certain brain networks and higher low-frequency fluctuations compared to healthy controls, which aligns with their attentional and psychomotor symptoms.

This study found that neonatal administration of allopregnanolone enhances, while finasteride suppresses, the effects of adult intrahippocampal pregnenolone sulphate on rat locomotor activity in an open field test.
