This review discusses the progress in identifying stem cells responsible for tissue regeneration and highlights technological advances in tracking their behavior, but reports no new clinical results.

This study reported new crystallographic structures and polymorphs of finasteride, including several solvates with distinct X-ray diffraction patterns and thermally characterized properties.

This study found that ZDHHC13 deficiency in mice is associated with abnormal liver function, lipid metabolism issues, and impaired mitochondrial function, highlighting ZDHHC13's regulatory role in liver metabolism.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This study found that T-regulatory cells, specifically the FOXP3 CD39 subset, were significantly reduced in both circulation and hair follicles of alopecia areata patients compared to healthy subjects, suggesting potential therapeutic targets.

This study found that scalp injection of fat enriched with stem cells may offer a promising alternative for treating early genetic alopecia in both men and women.

This study demonstrated that a 3D air–liquid culture system using Wnt-CM-treated cells can induce hair regeneration in nude mice and may facilitate large-scale preparation for hair loss treatment.

Human hair follicles have a unique metabolism that changes between growth stages and may contribute to baldness.

This study found that repeated oral intake of 0.5 or 5 mg/kg of cobalt ferrite nanoparticles induced pulmonary toxicity in rats, with dose-dependent oxidative stress and inflammation observed, but no notable toxicity was seen at a 0.05 mg/kg dose.

The document concludes that there are still unknowns about the effectiveness, risks, and detection of performance-enhancing drugs, and doping remains a challenge.

This review explores the diverse roles of rosemary, covering its nutritional and medicinal uses, cosmetic and pharmaceutical applications, and evaluates various extraction methods, with a focus on sustainable practices and commercial prospects.

This study found that the methanolic heartwood extract of Avicennia marina significantly inhibits 5α-reductase type 1, reducing 5α-DHT production by 52% in a cell-based assay with human hair dermal papilla cells.

This study reports on the biochemical characteristics of S100A3 protein in human hair cuticle, notably finding its N-terminal methionine is acetylated and has a slightly lower isoelectric point compared to the recombinant version.

Method accurately measures finasteride in tablets using finasteride-BSA interaction.

This review explores cannabigerol (CBG) as a potential therapeutic agent with various pharmacological activities but reports no new clinical results, emphasizing the need for further research on its efficacy and safety.

This study developed solid lipid nanoparticles for effective delivery of shRNA-encoding plasmids, showing reduced 5α-reductase levels in DU-145 cells without significant cytotoxicity.

This study observed that platelet-rich plasma samples from female patients show significant variability in growth factor secretion, which may influence the inconsistent clinical response in alopecia treatment.

This study found that sheep wool follicles actively oxidize acetate and glucose, suggesting the involvement of the TCA cycle for compound synthesis and the potential role of the pentose phosphate pathway in ribose production for RNA and DNA.

This study reported that the calculated and experimental electronic and vibrational properties of minoxidil were in good agreement, providing detailed insights into its molecular structure and thermal behaviors.

This study identified and characterized eight compounds, including furanocoumarins and pterocarpans, from the aerial parts of Bituminaria basaltica, with β-caryophyllene and germacrene D as main constituents of its essential oil.

This study reported that a newly developed UHPLC-MS/MS method detected illegal synthetic hair-growth compounds in 10% of 76 hair-growth products, highlighting the need for ongoing monitoring to protect public health.

This study synthesized and characterized new 2-hydroxypyrrolidine/piperidine derivatives using FeCl₃·6H₂O as a catalyst, but it reports no biological or clinical results.

This study reported that plant-produced basic fibroblast growth factor effectively promoted cell proliferation and collagen production in vitro, suggesting potential applications in cosmetics for antiaging and hair growth.

In this study, the PLP2 gene was found to promote secondary hair follicle development in Liaoning cashmere goats, with its expression negatively regulated by melatonin and potentially affecting follicle development via the BMP pathway.

This study found that both crude Spirulina extract and C-phycocyanin showed similar effects on keratinocyte proliferation and wound healing, with C-phycocyanin performing better in tissue regeneration in vivo on the 7th day.

This study demonstrated that using finasteride impurity as a non-isotopically labeled internal standard in paper spray ionization–mass spectrometry can effectively and efficiently measure finasteride tablet dissolution, achieving results comparable to high-performance liquid chromatography.

This study found that hair dyes significantly affect DNA sequence analysis, with the organic extraction method performing better on hair shafts and the prepFiler kit yielding higher success for follicle-included samples.

This review outlines the biological effects of various placental extracts, noting their reported antioxidant, anti-inflammatory, and immunomodulatory activities, but highlights that the relationship between these effects and the extracts' specific contents remains unclear.

This overview examines the biology, origin, structure, and function of various cells and structures, such as the blood-retinal barrier and Merkel cells, and discusses their roles in disease pathogenesis, along with recent findings related to the lymph nodes' paracortex.
