This study found that hydrophobic lipid-coated silica nanoparticles penetrated deeper into human stratum corneum compared to their hydrophilic counterparts, highlighting the influence of surface polarity on skin penetration.

Among Australian fur seals at one colony, this study found that alopecia, primarily affecting juvenile females, is linked to hair shaft fractures associated with low tyrosine and zinc levels, as well as higher pollutant exposure.

This study identified 77 genes with significant expression changes in expanded human skin, suggesting possible mechanisms for skin regeneration during tissue expansion, including previously unreported genes like HOXA5, HOXB2, and AP1.

This study reported that a novel chitosan/polyvinyl alcohol nanofiber sponge effectively enhances the hair follicle-inducing ability of dermal papilla multicellular spheroids in a mouse model.

This paper reviews the literature on acquired trichorrhexis nodosa, a clinical hair loss diagnosis associated with hair care practices, particularly in those with tightly curled hair, and emphasizes management through protective hair care regimens rather than traditional prescription therapies.

Nandrolone and oxandrolone could help treat male health issues like muscle loss and low testosterone.

This study found that electrophoretic keratin typing of head hair can identify specific polypeptide patterns, suggesting potential applications in genetic and forensic investigations.

This study found that during the Covid-19 lockdown, the percentage of abstinent and low-risk alcohol drinkers increased while moderate and chronic drinking decreased compared to the previous four years.

In this study, using light masks to extend photoperiod was effective for maintaining the summer coat in horses and accelerating shedding in outdoor horses, but timing was crucial for success.

In this study, luteolin-loaded nanoemulsions were shown to promote hair growth similarly to a luteolin solution in organic solvents, offering enhanced stability for follicular delivery.

This review discusses the analysis of pharmaceutical relics from prehistoric times to the twentieth century and emphasizes the need for a multifaceted approach, but it presents no new experimental results.

This article discusses the benefits of liposomes in cosmetic formulations, including enhanced hydration and protection for dry skin, but reports no new experimental findings.

This study found that keratins 5, 7, 8, and 19 are expressed in human trophoblast cells while vimentin is solely expressed in stromal-mesenchymal cells, aiding in placental cell type identification.

This study concluded that low-level fluence 810 nm diode laser therapy was generally well tolerated, safe, and effective for long-term hair reduction in a small sample of patients with various skin types.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This review discusses the relationship between gut microbiota and alopecia areata, and it does not report new clinical results.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

This study found that the n-hexane fraction from Leea indica leaves significantly increased hair growth in mice and showed potential as a natural treatment for alopecia.

This study found that Pannexin 3 plays a crucial role in skin development by regulating the transcription factor Epiprofin, affecting keratinocyte differentiation and hair follicle regeneration in mice.

In this study, human hair follicles showed varying expression of cholesterol transport proteins during the hair cycle, suggesting a potential role of cholesterol in hair growth and cycling.

This study found that finasteride impaired object recognition memory and altered hippocampal dendritic structures in male 3xTg-AD mice, suggesting potential sex differences in Alzheimer's disease pathology.

In this study, finasteride was found to inhibit the dopaminergic system and reduce open-field behaviors in adolescent male rats by decreasing dopamine levels and related proteins.

This study presents recombinant human hair keratins K31 and K81, observing novel nanostructures from their self-assembly and emphasizing disulfide crosslinking's role in this process.

This study found that quiescent bulge stem cells, when prevented from contributing to hair follicle and epidermal regeneration, did not affect hair follicle growth or wound healing in the short term.

Nanocarriers could improve how drugs are delivered through the skin but require more research to overcome challenges and ensure safety.

This review discusses the impact of COVID-19 on hormone therapy in gynecology, emphasizing the need for more high-quality evidence for individualized management, but it reports no new clinical results.

This study demonstrated that a new non-invasive method for collecting and analyzing mouse hair follicles could replace traditional biopsy methods, providing advantages for translational research and routine applications.

This study found that carvone, a plant-derived compound, decreases melanin content and inhibits melanoma cell proliferation through the cAMP pathway, suggesting potential benefits for treating melanomas and other hyperpigmentation disorders.

This review evaluated the evidence on skin disorders linked to levodopa treatment for Parkinson's disease, suggesting a possible association with melanoma, though evidence remains inconclusive and further studies are needed.

This study found that protein extracts from human hair demonstrated significant antioxidant abilities, protecting human dermal fibroblasts from oxidative stress, suggesting potential for biomedical applications.
