New treatments for male hypogonadism are effective and should be personalized.

This review discusses methotrexate's use in dermatology and its mechanisms, pharmacokinetics, dosing, side effects, interactions, and emphasizes the need for further research into optimizing therapy and predicting adverse events.

Created material boosts hair growth and kills bacteria for wound healing.

This review discusses the potential applications of adipose-derived stromal cells for treating conditions like colitis, liver failure, and more, without presenting new clinical results.

This study found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This study found that aging mice experience slower and more fragmented hair cycle waves, but transplanting aged skin to a young host can partially restore hair cycling, implicating extracellular factors.

This review discusses the use of mushrooms and their bioactive compounds in cosmeceuticals and nutricosmetics and reports no new clinical findings, highlighting potential areas for future research and development.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This study presents a novel in vitro assay using human folliculoid microspheres to research hair growth, which may facilitate preclinical testing of hair growth-modulatory agents.

This study reports that plasma rich in growth factors appeared to improve hair follicle regeneration and patient satisfaction in individuals with androgenetic alopecia, though further trials are needed.

This review discusses current knowledge on the biological mechanisms of different types of alopecia but reports no new clinical findings; the authors highlight future research directions, especially regarding epidermal stem cells and immune pathways.

This study explored the interaction between androgen and Wnt signaling in dermal papilla cells, targeting the effects of androgen on hair growth reduction.

This study found that the binding of finasteride to the enzyme 5a-reductase occurs at a slower rate than previously assumed, complicating the estimation of its real inhibitory constant.

This review assesses the benefits and limitations of various supramolecular hydrogels, including polymeric and peptide-based types, for wound healing, but reports no new clinical results.

This study found that in vivo, a novel microneedle system for valproic acid delivery may improve hair regrowth efficacy by upregulating hair follicle development pathways more effectively than topical application.

This study found that in thin cutaneous melanomas, tumor regression is associated with a higher risk of sentinel lymph node involvement.

This study found that overexpression of Hoxc13 in GC13 mouse models affects hair follicle differentiation by interacting with medulla-specific genes, particularly Foxq1, suggesting a regulatory pathway for medulla differentiation.

Pregnancy often causes skin changes like darkening, stretch marks, and hair growth, which may improve after childbirth.

This review found that patients with alopecia areata may have lower levels of vitamin D, zinc, and folate, but conflicting evidence precludes definitive clinical recommendations for micronutrient supplementation.

This study found that 3D microtissue models of dermal papilla cells can enhance the ability to induce hair-follicle neogenesis in vivo, offering potential for controlled cell production in follicle regeneration.

This study found that the multifunctional FEA-PCEI dressing significantly accelerated wound healing, reduced scar formation, and promoted hair follicle neogenesis while providing antibacterial and anti-inflammatory benefits.

This study found that dual inhibition of BACE1 and BACE2 in mice affects melanosome maturation and causes dose-dependent hair depigmentation without altering retinal morphology.

This review discusses various substances that can impact male fertility and stresses that products should be confirmed 'sperm-safe' through rigorous testing, not assumptions; it reports no new study results.

This study reported that administering lufenuron to dogs and cats effectively and rapidly resolved fungal infections within about 21 days for dogs and 12 days for cats, compared to around 90 days in untreated controls.

This review discusses photothermal agent hybrids in hydrogels for antibacterial action, angiogenesis, and osteogenesis in tissue engineering, but reports no new experimental findings.

This study found that overexpression of the transcription factor Tcf3 accelerates keratinocyte migration and skin wound healing in mice, highlighting its potential as a therapeutic target for wound repair.

This review discusses pharmacologic and non-pharmacologic treatments for androgenetic alopecia, noting that current medications like finasteride and minoxidil can slow hair loss but only partially restore hair growth, with early treatment offering better outcomes.

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This review discusses recent advances in monophosphate prodrug strategies for HCV drug discovery, aiming to enhance oral absorption and stability, and reports no new clinical results.
