This study suggests that altering levels of the neurosteroid allopregnanolone during neonatal stages in rats may impact alcohol consumption and dopamine release in adulthood, indicating potential effects on alcohol reward properties.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

This study found that a specific amino-pyridine compound showed potent androgen receptor antagonist activity, stimulating hair growth in mice and reducing sebum production in a hamster model.

This study found that cold air can effectively preserve the epidermis when using an 810 nm diode laser, but it is slightly less effective than a chilled sapphire window in dark-haired pigmented pigs.

The study suggests that CO₂ laser creates hair transplant channels with significantly less lateral thermal damage than Ho:YAG laser in the human scalp.

This background review discusses alopecia areata, highlighting the role of CD8+NKG2D+ T cells in hair follicle pathogenesis, and notes that the exact mechanisms causing hair loss remain unclear.

In this study, researchers identified a novel homozygous variant in the FAM83G gene responsible for autosomal recessively inherited palmoplantar keratoderma with curly hair in a consanguineous Pakistani family, suggesting FAM83G plays a crucial role in skin and hair homeostasis.

This review highlights recent advances in personalized transdermal drug delivery systems, noting their potential for improved treatment efficacy and safety, but identifies significant challenges in clinical translation.

In this study, researchers created a detailed human skin cell atlas by analyzing over 700,000 cells, finding that disrupted communication among specific immune and stromal cell subsets may play a key role in initiating and sustaining chronic skin inflammation in atopic dermatitis.

This study optimized a screening assay to identify molecules that inhibit or enhance TRPM5 ion channel activity, which may have implications for treating dysfunctions linked to cardiac arrhythmias and diabetes.

This study identifies a bipotent stem cell in adult hair follicles that self-renews and contributes to dermal sheath and papilla cell populations, potentially aiding hair regrowth after injury, disease, or aging.

This review discusses the potential link between early postnatal allopregnanolone levels and vulnerability to drug abuse in adulthood, noting a need for more in-depth studies to confirm this relationship.
