In this study, researchers found that in late pregnancy, the neuroactive progesterone metabolite allopregnanolone inhibits HPA axis responses to immune challenges via an opioid-mediated mechanism.

This study found that testosterone and dihydrotestosterone are crucial for synaptic transmission and spine density in male hippocampal neurons, suggesting sex-specific effects of neurosteroids on brain development.

This study found that both ethanol and aqueous extracts of Lepidium sativum seeds improved insulin signaling and reduced obesity-related metabolic changes in high-fat diet-fed rats, suggesting potential as a dietary supplement.

This study demonstrated that troxerutin may protect human dermal papilla cells from H2O2-induced damage and suggests potential in treating alopecia by inhibiting ROS-mediated cellular damage.

In this study, male-derived brain tissue exhibited higher cell death following ischemia compared to female-derived tissue, and certain steroid hormones showed different neuroprotective effects depending on the sex of the tissue.

In this study, the researchers observed that biotin administration in biotin-deficient children with alopecia eliminated certain membrane proteins from their blood, suggesting that biotin might regulate these proteins' expression.

In this study, a newly developed polyherbal hair oil exhibited promising characteristics, including a beneficial pH and antimicrobial activity against Staphylococcus aureus, with preliminary tests suggesting it supports scalp and hair health without adverse effects.

This study found that finasteride may improve pulmonary and hepatic immune responses in mice when administered after major trauma and hemorrhage.

This study found that selective deletion of Ctip2 in epidermal keratinocytes in adult mice leads to atopic dermatitis-like inflammation and suggests Ctip2 plays a crucial role in skin barrier maintenance and inflammatory regulation.

Finasteride helps treat hair loss by blocking enzyme activity.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

This study found that prostaglandin D2 reduced proliferation in bulge resident K15+ stem cells but not in other K15+ progenitor cells, suggesting differential impacts on hair follicle stem cell niches.

This study introduced the dual-flow-RootChip platform to demonstrate that Arabidopsis roots exhibit non-autonomous adaptations, such as hair growth regulation, when subjected to varied environmental conditions on opposite sides.

This study found that maternal consumption of a western diet in mice led to toxic milk production, causing inflammation and alopecia in nursing neonates due to Toll-like-receptor activation.

This review discusses the evolution of lineage-tracing strategies over the past century, emphasizing their role in identifying progenitor cells and resolving debates about cellular origins, with no new results reported.

This review examines diverse regenerative strategies in animals and highlights how biochemical, immunological, and mechanical signals can work together for successful skin regeneration in adult mammals, but it reports no new experimental results.

This study identified the NAC transcription factor RD26 as a critical regulator of drought-induced root hair growth restriction in Arabidopsis thaliana, with a similar mechanism observed in tomatoes, indicating evolutionary conservation.

This review discusses the heterogeneity of dermal fibroblasts in healthy mouse and human skin and reports no clinical results; the authors highlight potential insights into physiological and pathological wound healing.

This study mapped the development of the human pilosebaceous unit in prenatal scalp skin using multi-modal analysis, finding that epithelial-mesenchymal interactions guide cellular fate and validated tissue-patterning through a hair-bearing skin organoid model.

This study found that mice lacking syndecan-1 experienced cold stress and metabolic issues due to reduced intradermal fat, which was restored by thermoneutral housing or rosiglitazone treatment.

This article discusses the roles of epidermal stem cells in maintaining skin homeostasis and highlights how deregulation in signaling pathways may lead to cancer, but it reports no new experimental results.

Skin stem cells maintain and repair the outer layer of skin, with some types being essential for healing wounds.

This abstract omits specific findings and does not provide new research results.

This review introduces an integrated view of hair follicle behavior, highlighting a Yin Yang model of regulation and suggesting glycans as key elements in hair follicle growth control, without reporting new clinical findings.

Genetic research has advanced our understanding of skin diseases, but complex conditions require an integrative approach for deeper insight.

In this study, researchers found that microglia play a crucial role in neurogenesis and brain regeneration in zebrafish by regulating inflammatory signaling, and their absence impairs these processes.

This study provided insight into unexpected uses and abuse of oral contraceptive pills by Jordanian males, primarily for bodybuilding, as reported by community pharmacists.

In this theoretical study, the authors developed a computational model to explore whether a reaction-diffusion process could explain the signal inducing axolotl spinal cord regeneration, proposing that regeneration control depends on cell sensitivity to the signal and its diffusion characteristics.

This study found that MAPK/ERK signaling plays a key role in driving tissue regeneration in spiny mice and suggests potential for reversing fibrosis to promote regeneration in mammals.

This study found that low temperatures and nitrogen deficiency trigger root hair elongation through a molecular mechanism involving the receptor kinase FERONIA and the TOR Complex 1.
