This study found that standard decontamination procedures may not fully remove external contamination in post mortem hair specimens, complicating the interpretation of drug detection in such samples.

This study observed no teratogenic effects of oral decongestants and surprisingly favorable neonatal outcomes in Swedish women who used them during pregnancy.

Psoriasis treatments range from topical creams to systemic medications with serious side effects, and while treatments can manage symptoms, there is no cure.

This chapter reviews dermatological drugs and cosmetics, identifying common allergens and preservatives linked to contact dermatitis without reporting new clinical results.

In this study, extracts of Zataria multiflora Boiss. and Matricaria chamomilla, combined with minoxidil, significantly improved hair growth in androgenetic alopecia patients by potentially inhibiting 5α-reductase activity.

This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.

This review explores androgen metabolism in the skin, highlighting enzyme localization and potential implications for treating androgen-dependent skin conditions, but it reports no new clinical results.

This article proposes five different mechanisms for telogen effluvium, supported by clinical findings, based on changes in different phases of the hair cycle.

This review discusses the interplay of hyperandrogenism, insulin resistance, obesity, and their role in polycystic ovary syndrome, but presents no new clinical results.

This study found that fluoxetine did not demonstrate short-term efficacy in treating trichotillomania in a placebo-controlled, double-blind crossover setting.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

This study found that neuroactive steroids like DHEA and pregnenolone influence cocaine-induced appetence in mice through their interaction with the ς₁ receptor, suggesting a role in individual vulnerability to addiction.

This review discusses the potential role of steroid 5α-reductase inhibitors in treating neuropsychiatric disorders related to dopaminergic hyperreactivity but reports no new clinical results.

In this study, bleaching and perming were found to significantly reduce opiate concentrations in both spiked and naturally opiate-positive human hair samples.

This study developed and validated a high-resolution mass spectrometry method to screen for prohibited substances and analyze six endogenous steroids in urine according to World Antidoping Agency requirements, demonstrating its effectiveness for antidoping analysis.

The LRRK2-G2019S mutation in Parkinson's disease has a lifetime penetrance of 25-35%, and finasteride may help reduce symptoms in adult male Tourette syndrome patients.

This article contains additional supporting information available online but presents no new research findings.

This study found that leptin acts as an inducer of the anagen phase in hair follicles, suggesting its role as a potential player in hair biology.

This study identified four circRNAs with significantly different expression levels in Liaoning cashmere goats, suggesting a potential role in regulating cashmere fineness.

Finasteride may help reduce symptoms in male Tourette syndrome patients.

In this study, socially defeated mice showed increased alcohol consumption, and CRF-R1 antagonism selectively reduced drinking in these mice, suggesting a potential treatment target for stress-related alcohol use disorders.

In this study, several compounds, including estrogen and Dutasteride, showed neuroprotective effects on dopaminergic neurons in an MPTP mouse model of Parkinson's disease.

This article reviews the triggers, diagnosis, and management of telogen effluvium in men and women, emphasizing the role of patient education and reassurance, but presents no new clinical findings.

This study found that cepharanthine can inhibit gastric cancer cell activity by inducing oxidative stress and altering energy metabolism, suggesting its potential for gastric cancer treatment.

The document describes a woman with familial Parkinson's disease due to a genetic mutation, showing severe symptoms and poor response to treatment, and suggests finasteride may help reduce symptoms in Tourette syndrome.

This study found that Dutasteride, a 5α-reductase inhibitor, demonstrated neuroprotective effects by preventing the MPTP-induced decline of dopaminergic markers in a Parkinson's disease mouse model.

This study found that both finasteride and dutasteride significantly reduced L-DOPA-induced dyskinesia in a rat model of Parkinson's disease, with dutasteride showing greater effectiveness at lower doses.

This article reviews various hair abnormalities in adolescents and young adults and emphasizes the importance of timely diagnosis and education for optimal patient outcomes, but it reports no new clinical results.
