This review suggests that skin may largely protect itself from CYP-generated reactive metabolites due to higher conjugating enzyme activities, while highlighting limitations in modeling human skin metabolism experimentally.

The document concludes that research on sulfatase inhibitors should continue due to their potential in treating various diseases, despite some clinical trial failures.

This study found that gels containing glycyrrhizic acid and aqueous Glycyrrhiza glabra extract significantly reduced underarm hair growth in terms of area, thickness, length, and number compared to their gel bases.

In this study, researchers identified key mRNA and microRNA regulatory mechanisms that influence cashmere growth in cashmere goats under different photoperiods, potentially offering new methods to enhance cashmere production.

Natural products might help treat hair greying.

This review explores the cellular and molecular basis of wound-induced hair neogenesis and its relationship with aging but does not report new clinical results, highlighting areas for future research.

This review highlights the role of all-trans retinoic acid in regulating stem and progenitor cell proliferation and differentiation, suggesting its potential to enhance treatments in regenerative medicine and cancer.

This study found that the combination of letrozole and quercetin loaded in spanlastics showed enhanced cytotoxicity and other anticancer effects against MCF-7 breast cancer cells compared to individual treatments.

In this study, researchers developed a new topical atraric acid formulation, AA-TF#15, which showed a significantly higher drug penetration and increased hair regrowth in mice compared to minoxidil and finasteride treatments, suggesting its potential effectiveness for treating scalp androgenic alopecia.

This review describes how liver and kidney diseases and diabetes may affect ethyl glucuronide levels in hair, impacting forensic and clinical interpretations, but reports no new experimental results.

This review concludes that while many epidemiological studies suggest high alcohol intake is associated with an increased risk of prostate cancer, the evidence may be affected by confounding factors such as diet and lifestyle.

This review discusses using extracellular vesicles as less invasive surrogates for assessing drug-metabolizing enzymes and transporters, suggesting potential advancements in precision therapy, but reports no new clinical results.

This review discusses the pharmacology, toxicology, and clinical efficacy of flavonoids and saponins, highlighting the need for more data on their pharmacokinetics, interactions, and toxicities as most research is still in vitro.

This study found that activating ALDH2, an enzyme that detoxifies acetaldehyde, promoted hair growth in hair follicles by reducing oxidative stress and enhancing cellular signaling pathways, suggesting a potential therapeutic approach for inducing hair regrowth.

The anti-hangover product may boost enzyme activity to help prevent brain damage.

This study found that mouse skin can produce and metabolize serotonin and N-acetylserotonin, with activity influenced by location, physiological skin status, cell type, and mouse strain.

This study found that the CD44(+) ALDH(+) population of neonatal human keratinocytes exhibited enhanced stem cell properties, including significantly increased long-term epidermal regeneration and multipotency, compared to unfractionated cells.

This review discusses the role of proteomics in understanding skin diseases such as cancers and psoriasis, with findings suggesting cell death and metabolism as major areas of focus, but reports no new experimental results.

In this study, the reconstructed skin epidermal model derived from hair follicles showed gene expression and enzyme functionality consistent with native human skin, suggesting its viability for studying skin metabolism and potential toxicity of dermo-cosmetic ingredients.

This report describes a case of Birt-Hogg-Dube syndrome with manifestations including multiple fibrofolliculomas, acrochordons, and renal oncocytoma.

In this study, two unrelated Honduran patients with Sjögren-Larsson syndrome had the same genetic mutation but displayed different disease severities, suggesting that factors beyond the ALDH3A2 mutation influence clinical outcome.

This study found that the ethanol patch test effectively indicates the ALDH phenotype in healthy Japanese individuals, suggesting its usefulness for future research.
