This review revisits mechanisms underlying acne lesion formation and suggests that preventing comedone development requires controlling critical factors in the pilosebaceous follicle before acne involvement.

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 reported that targeted anticancer therapies are associated with an increased risk of alopecia compared to placebo, although the risk was lower compared to chemotherapy.

This review discusses the mechanisms and engineering techniques for enhancing the targeted delivery of extracellular vesicles in therapies but reports no new clinical findings; the authors encourage further exploration to advance clinical applications.

This review discusses various cutaneous side effects potentially linked to oral contraceptive use but provides no new clinical results, emphasizing the need for more evidence in certain associations.

Many recovered COVID-19 patients in Saudi Arabia still experience symptoms like fatigue and anxiety, especially older adults and those with other health issues.

Finasteride may help reduce symptoms in male Tourette syndrome patients.

This review discusses the pharmacological properties and physiological regulation of neuroactive steroids, focusing on their varied responses to stress and ethanol in rats, mice, and humans, but it reports no new findings.

In this study, finasteride altered acute ethanol withdrawal severity differently in male and female mice, highlighting sex differences in sensitivity to changes in neurosteroid levels.

This review discusses the dual role of cellular senescence in ageing and tissue repair and suggests potential therapeutic applications, with no new experimental results reported.

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.

Finasteride reduces alcohol withdrawal effects, especially in female mice.

This study found that early life stress significantly affects hedonic sensitivity to high-palatable food by altering gonadal hormones in prenatally-stressed male and female rats, with sex-dependent changes in reward-related behaviors and neurochemistry.

This article reviews the impact of natural fungal pathogens on laboratory animal research and reports no new results, calling attention to infection risks with dermatophytes, Candida, and pneumonia in immunocompromised rodents.

This review examined dermatologic symptoms associated with COVID-19 in 2,560 patients, with chilblains/pernio-like lesions being the most common, suggesting these symptoms may aid in early identification of cases.

This study found that altering neonatal neurosteroid levels affected anxiety and aversive learning in adult rats, possibly through changes in hippocampal GABAergic functions.

This study found that testosterone treatment in older hypogonadal men caused minor improvements in depressive symptoms and visuospatial memory, but overall, major cognitive benefits were not observed.

This study reported that prenatal exposure to dihydrotestosterone altered long-term androgen metabolism in juvenile male rats, suggesting different regulatory mechanisms for 5a-reductase in hypothalamic versus pituitary tissues.

The new system can grow hair in the lab and test hair growth treatments.

This study reports that biomass activated carbon fibers derived from metaplexis japonica seed hair effectively adsorb methylene blue dye, demonstrating high capacity and rapid adsorption performance.

This review discusses the interactions between melanocyte stem cells and their niche in hair regeneration and repair, but reports no new results; recent studies on molecular pathways are highlighted.

This study found that finasteride affected ethanol withdrawal severity differently in WSP and WSR lines, with more modulation seen in the WSP line.

This study suggests that synthetic steroid analogues or 5α-reductase modulation could be potential therapeutic strategies for nervous system disorders, but further research on their effects is necessary.

The authors reviewed the mechanisms behind Kennedy's disease, noting advances in therapeutic strategies such as androgen deprivation and gene silencing that may soon expand treatment options for this incurable neuromuscular condition.

This study found that finasteride significantly improved motor, EEG, and cellular changes in a rat model of thioacetamide-induced hepatic encephalopathy and prevented the development of hepatic coma.

Finasteride significantly reduced tics and obsessive-compulsive symptoms in patients with Tourette syndrome.

This review discusses common skin eruptions caused by biologics in treating inflammatory bowel disease and proposes tailored therapeutic approaches for managing these adverse reactions.

This review identifies FDA-cleared home-use photobiomodulation devices for androgenetic alopecia treatment and highlights their excellent safety profile but notes the lack of long-term comparative studies.

This study found that finasteride significantly reduced dihydrotestosterone levels but did not provide clear evidence of impaired libido or erectile function compared to placebo in men.
